Wallpaper removal and drywall repair in older homes might seem like straightforward home improvement tasks, but without the right techniques, they can quickly become frustrating, costly, and pose health risks like respiratory issues. Whether it’s a DIY project or you’re hiring a professional wallpaper removal service, understanding what not to do is just as important as knowing the proper steps.

Here are seven most common mistakes homeowners in West Hartford, CT, should avoid when removing wallpaper and repairing drywall in older homes. 

1. Skipping Adhesive Test 

Not all wallpaper adhesives respond the same way—some dissolve with water or steam, while others resist even strong solvents. Skipping the adhesive test before wallpaper removal can lead to drywall damage, wasted time, and costly repairs. In older homes throughout West Hartford, CT, multiple wallpaper layers or strong adhesives are common, making it essential to test first for a safe, efficient removal.

Before jumping into full-scale wallpaper removal, conduct a simple adhesive test. Choose a small, inconspicuous spot—like behind a door or near the baseboard—and follow these steps:

• Score the wallpaper lightly using a wallpaper scoring tool. This allows moisture to penetrate through the adhesive layer.
• Apply warm water or a wallpaper remover solution using a spray bottle or sponge. Let it sit for 5–10 minutes.
• Gently attempt to peel the wallpaper back using a plastic scraper or putty knife.
• Observe how the adhesive reacts. If the wallpaper lifts easily in large strips, the glue is likely water-soluble. If it resists, you may need a steamer or stronger remover.
• If the wallpaper appears to have a vinyl or foil surface that repels water, perforating it first is essential for proper saturation.

How Wallpaper Type Affects Removal

Understanding the type of wallpaper also affects the removal method. If you’re unsure, a home wallpaper removal expert can identify it during a consultation. Here are a few common types:

• Peel-and-stick wallpaper: Usually comes off cleanly without residue—minimal testing needed.
• Vinyl wallpaper: Moisture-resistant and requires scoring before water application.
• Fabric-backed wallpaper: Strong adhesive and heavy-duty material often need steaming or professional tools.
• Painted-over wallpaper: Often seals the glue underneath, making removal significantly harder.

2. Using Incorrect Tools

One of the most common and costly mistakes homeowners make during wallpaper removal is using the wrong tools—or worse, using whatever is on hand. Kitchen knives, metal putty knives, or sharp blades may seem convenient, but these makeshift tools can gouge or tear the drywall beneath the wallpaper. This often results in uneven wall surfaces that require patching, sanding, and in some cases, full drywall repair.

In aged homes in West Hartford, CT, the drywall may already be fragile or poorly primed, increasing the risk of serious damage when improper tools are used.

Must-Have Tools for Safe and Efficient Wallpaper Removal

To remove wallpaper without damaging the wall, homeowners should equip themselves with the following tools:

• Wallpaper scoring tool – Lightly perforates the surface of the wallpaper, allowing moisture or solution to reach the adhesive beneath.
• Plastic or flexible wallpaper scraper – Designed to lift wallpaper gently without tearing or digging into the drywall.
• Spray bottle or pump sprayer – For applying warm water or a home wallpaper removal solution evenly.
• Wallpaper steamer (for tough adhesives) – Loosens stubborn glue with heat and moisture, especially useful for vinyl or layered wallpaper.
• Drop cloths and painter’s tape – Protects flooring and trim from water drips and debris during removal.

Common Tool Mistakes That Can Ruin Your Walls

Many homeowners make the mistake of using sharp or rigid metal tools—like putty knives or utility blades—for wallpaper removal. While these may seem effective at first, they often cause more harm than good by:

• Scratching or gouging the drywall surface
• Tearing the paper facing the drywall
• Creating uneven spots that show through paint or new wallpaper
• Increasing the need for costly repairs and extended prep time before refinishing

Why Professional Tools Make a Difference

A professional wallpaper removal service in West Hartford, CT, comes prepared with commercial-grade tools and techniques that go beyond the average DIY kit. These include services for the best wallpaper removal near me include:

• High-powered steamers that deliver consistent heat and moisture
• Non-abrasive scrapers that protect delicate wall surfaces
• Specialty blades for precision removal of edge or corner sections
• Industrial vacuums and cleanup tools for efficient, dust-free removal

3. Over-saturating the Drywall with Water

Many homeowners mistakenly believe that more water speeds up wallpaper removal. In reality, oversaturating the wall can cause a range of problems—especially in older homes, where drywall and plaster surfaces are often more fragile. Using too much water can:

• Soften or crumble drywall
• Weaken the wall’s surface paper, creating soft spots
• Encourage mold or mildew growth from trapped moisture
• Cause bubbling or cracking when new paint or texture is applied
• Lead to longer drying times and costly delays in your renovation

How to Apply Water the Right Way

To loosen wallpaper without damaging the wall, apply water gradually and precisely. Searching for the best wallpaper removal near me in West Hartford, CT, ensures quality results. Professionals recommend the following steps:

• Lightly mist the wallpaper using a spray bottle or pump sprayer
• Allow moisture to sit for several minutes before scraping
• Work in small sections to prevent oversaturation
• Reapply moisture as needed, not all at once
• Use a sponge for controlled application around corners and edges

4. Not Repairing the Drywall Properly After Removal

Failing to properly repair drywall after wallpaper removal is a mistake that can compromise the final finish of any wall. Wallpaper adhesives often leave behind residue, minor gouges, or torn drywall paper. If these imperfections aren’t addressed, they’ll remain visible under fresh paint or new wallpaper—and can even worsen over time due to bubbling, peeling, or uneven textures.

This is especially common in aged and historic houses throughout the city, where drywall may already have existing wear or prior damage. Skipping repair not only affects aesthetics but also reduces the durability of your new finish.

Common Signs Your Walls Need Repair

After removing the wallpaper, look for these indicators that the drywall requires attention:

• Residual adhesive or glue film left on the surface
• Torn drywall paper where the wallpaper pulled off too aggressively
• Surface gouges or scratches from scraping tools
• Uneven patches or bumps that can interfere with smooth painting

What to Do Instead

To ensure a smooth, professional-looking surface, follow these essential repair steps:

Clean the Walls Thoroughly

Use a mild adhesive remover or warm water with a small amount of dish soap to clean off glue residue. Rinse and allow the wall to dry completely.

Patch and Skim Coat

Apply joint compound (also known as drywall mud) to fill in dents, torn areas, or shallow gouges. A full skim coat may be necessary for larger or uneven sections.

Sand Smooth

Once the compound dries, sand the surface lightly to create a consistent, flat finish. Use a sanding block or pole sander for even results.

Prime the Wall

Apply a high-quality drywall primer to seal the surface, especially over patched areas. This step ensures better paint adhesion and an even finish.

5. Skipping Primer Before Painting or Re-wallpapering

One of the most overlooked—but most critical—steps after wallpaper removal and drywall repair is priming the wall before applying paint or new wallpaper. Bare or freshly patched drywall tends to absorb paint unevenly, leading to a blotchy, streaked, or dull finish. Likewise, applying wallpaper directly to unprimed drywall or joint compound can cause poor adhesion, which increases the risk of peeling or bubbling within weeks.

Primer acts as a barrier, sealing the surface and creating a consistent base for paint or adhesive. Skipping this step in home wallpaper removal compromises the final appearance and durability of your wall treatment—resulting in more work (and expense).

The Risks of Skipping Primer

When the primer is ignored, homeowners may experience:

• Uneven paint absorption that results in visible lap marks and patchy color
• Mismatched sheen or finish, especially over joint compound or sanded areas
• Poor wallpaper adhesion, leading to air pockets, seams, or peeling
• Difficulty removing future wallpaper due to direct contact with drywall
• Long-term wall damage, particularly in humid areas like bathrooms or kitchens

Best Priming Practices for a Smooth Finish

To ensure proper surface preparation, follow these steps:

Choose the Right Primer

For painting, use a high-quality drywall primer to seal the surface and ensure even color distribution. For wallpapering, use a primer-sealer to create a slick, non-porous surface that allows for easier future removal.

Apply After All Repairs are Complete

Ensure all joint compound is fully dry and sanded smooth before applying primer.

Use the Right Tools

A roller is ideal for large areas, while a brush can help cut in edges. Apply a consistent coat without overworking the product.

Let It Cure Fully

Follow the product’s drying time before proceeding with paint or wallpaper to ensure proper adhesion.

6. Underestimating the Time and Labor Required

Wallpaper removal and drywall repair are far more demanding than they appear. Many homeowners assume it’s a quick weekend project, only to find themselves overwhelmed by the time, physical effort, and attention to detail involved. Rushing through the process often results in:

• Sloppy removal techniques that tear drywall or leave adhesive behind
• Missed preparation steps like cleaning, repairing, and priming
• Uneven or damaged walls that require extensive rework
• Delays in painting or re-wallpapering due to lingering issues or moisture

Why Hiring a Pro Saves Time and Hassle

Many homeowners in West Hartford, CT, search for the best wallpaper removal near me and turn to experienced professionals for good reason. Reputable contractors come prepared with the right tools, proven methods, and efficient workflows that dramatically reduce project time—without sacrificing quality.

• Faster turnaround times, thanks to trained crews and commercial-grade equipment
• Clean, damage-free results that don’t require touch-ups or rework

7. Not Hiring a Professional When Necessary

While a DIY approach may seem like a budget-friendly solution, it often ends up being more expensive and time-consuming when the job goes wrong. Wallpaper that was improperly installed, applied over unprimed walls, or layered with paint can be extremely difficult to remove without causing damage. Add in fragile drywall, unique textures, or structural imperfections, and you’re looking at a project that can quickly spiral out of control.

In situations like these, untrained removal methods can lead to torn drywall paper, uneven surfaces, mold exposure from over-wetting, or the need for full wall replacement. Especially in aged, traditional houses across West Hartford, CT, where wall conditions can vary significantly, knowing when to call in a professional is critical.

When deciding between DIY wallpaper removal and hiring a professional, it’s important to consider both the risks and costs. Although a DIY approach may appear cheaper upfront, improper techniques can damage your walls, leading to costly repairs. On average, professional wallpaper removal services cost between $422 and $1,190, depending on factors like room size and wallpaper type.

How to Prepare a Space Before Wallpaper Removal

Proper preparation is key to a smooth and damage-free wallpaper removal process. Without it, homeowners risk unnecessary mess, damage to floors and trim, or delays that can complicate the project. Preparing the room ahead of time ensures efficiency, protects surfaces, and sets the stage for successful drywall repair and finishing.

Steps for Effective Room Prep

Clear the Area

All furniture should be removed from the room or moved to the center and covered with protective plastic. Wall art, switch plates, and outlet covers should be taken down to allow full access to the wallpapered surface.

Protect Floors and Fixtures

Drop cloths or plastic sheeting should be used to cover flooring, baseboards, and adjacent surfaces. Painter’s tape can help seal edges and prevent water or adhesive remover from seeping into sensitive areas.

Shut Off Electrical Outlets

If wallpaper removal takes place near electrical outlets or switches, turning off power to those areas is a smart precaution—especially when water or steam is involved.

Have the Right Tools Ready

Preparation includes organizing all necessary tools ahead of time, such as a scoring tool, scraper, spray bottle or steamer, sponges, adhesive remover, and towels. This prevents disruption once the removal begins.

How West Hartford Pros Assess Wallpaper Before Removal

Trusted contractors offering professional wallpaper removal in West Hartford, CT, always begin with adhesive testing. It’s a crucial step in assessing:

• The most effective removal method (manual, chemical, or steam)
• The type and condition of the adhesive
• Whether the wall was primed before wallpaper application
• Any risk of hidden drywall damage

How Skipping the Adhesive Test Can Damage Your Walls

Neglecting to test the adhesive before removal can result in:

• Drywall tearing from aggressive scraping on stubborn wallpaper
• Overuse of water or steam, leaving drywall saturated and soft
• Surface bubbling or mold from trapped moisture and leftover glue
• Extended labor time due to trial-and-error removal methods
• In severe cases, full drywall replacement if the paper facing is compromised

How Professionals Do It Better

Hiring a professional wallpaper removal service means gaining access to specialized tools, expert techniques, and years of hands-on experience with affordable wallpaper removal. These professionals don’t just remove wallpaper—they assess wall conditions, minimize risk, and ensure surfaces are left clean and ready for the next finish.
Here’s what sets the pros apart:

• Moisture meters to accurately measure wall saturation and prevent over-wetting, which can damage drywall
• Industrial-grade steamers designed to tackle thick, multi-layered, or vinyl-coated wallpaper with ease
• Precision scoring tools that penetrate adhesive layers without harming the wall surface
• Commercial adhesive removers formulated to break down specific glue types without residue or damage

Frequently Asked Questions

What should I do before starting wallpaper removal to avoid damaging my walls?

Always begin with an adhesive test. This helps determine how the wallpaper responds to moisture or removal solutions. Skipping this step is one of the most common causes of torn drywall and unnecessary damage.

Can too much water ruin my drywall during wallpaper removal?

Yes. Oversaturating the wall can weaken the drywall, cause bubbling, and promote mold growth. A light, controlled misting is best. Professional wallpaper removal services use tools and techniques that limit moisture exposure while effectively loosening the adhesive.

Is it necessary to repair drywall after the wallpaper is removed?

Absolutely. Most walls will have leftover adhesive, nicks, or torn drywall paper that must be patched, skim-coated, sanded, and primed. Skipping this step leads to visible flaws in your final finish and can shorten the lifespan of your paint or new wallpaper.

Why is a primer crucial after drywall repair?

Primer seals patched areas and ensures even paint or wallpaper adhesion. Without it, surfaces can absorb paint unevenly or cause new wallpaper to peel. Skilled contractors always include primer in their prep process for a flawless, long-lasting finish.

When is hiring a professional better than DIY wallpaper removal?

DIY works for simple jobs, but you should hire a pro if your walls have multiple wallpaper layers, painted-over wallpaper, or underlying damage. Professionals in West Hartford, CT, like Custom Colonial Painting, ensure safe removal, full drywall repair, and a clean, paint-ready surface—saving time, stress, and costly repairs.
