Our Drywall Services

Drywall Installation

Whether you're finishing a basement, renovating an older home, building a secondary suite, or completing a commercial fit-out, we install durable drywall systems with precise framing alignment, taping, mudding, sanding, and paint-ready finishes for long-lasting performance.

Drywall Repair & Ceiling Restoration

From small holes and settlement cracks to damaged ceilings caused by roof leaks, ice dams, and everyday wear, we restore walls and ceilings to a seamless finish with expert patching, texture matching, and plaster-to-drywall replacement.

Water Damage Drywall Restoration

Water intrusion from burst pipes, condensation, roof leaks, or flooding can quickly weaken drywall and encourage mould growth. We remove damaged materials, replace affected drywall, and restore clean, durable walls and ceilings ready for repainting.

Basement Drywall Finishing

Our drywall finishing specialists provide clean joints, smooth corners, skim coating, and Level 4 or Level 5 finishes that eliminate visible seams and prepare your walls and ceilings for high-quality paint or decorative finishes.

Commercial Drywall Services

We provide professional drywall installation, repairs, restoration, tenant improvements, and fire-rated wall systems for offices, retail spaces, healthcare facilities, schools, warehouses, and commercial buildings throughout Thunder Bay and Northwestern Ontario.

Repair or Replace Your Drywall?

Repair Your Drywall If...

  • Small holes, settlement cracks, nail pops, dents, ceiling stains, or minor water damage are limited to isolated areas.


  • Water damage from roof leaks, ice dams, condensation, or burst pipes has been addressed promptly and the drywall remains structurally sound.


  • You need seamless patching after plumbing, electrical, HVAC, insulation, mould remediation, or restoration work.


  • You're preparing your home, cottage, rental property, or commercial space for painting, resale, a new tenant, or occupancy.

Replace Your Drywall If...

  • Water intrusion has caused swelling, mould growth, sagging ceilings, delamination, or deterioration beyond practical repair.


  • You're restoring your home after flooding, major roof leaks, burst pipes, fire damage, or completing an insurance restoration project.


  • Existing drywall has widespread patchwork, outdated plaster, recurring moisture damage, or uneven surfaces that prevent a quality finish.


  • You're upgrading to moisture-resistant, mould-resistant, soundproof, impact-resistant, or fire-rated drywall for improved long-term performance.

Not Sure Which Option Is Best?

Whether you own an older home in Northwood, Grandview, College Heights, or Vickers Heights, a newer property in Parkdale or Confederation Heights, or a commercial building along Balmoral Street or Central Avenue, the right solution depends on the extent of the damage, moisture exposure, and your long-term renovation goals. We'll carefully inspect your drywall and recommend the most practical, cost-effective repair or replacement solution.

Drywall Solutions For Renovations, Basement Apartments & Commercial Fit-Outs

Moisture-Resistant Drywall For Basements & Laundry Rooms

Ideal for finished basements, laundry rooms, utility spaces, and areas with elevated humidity, moisture-resistant drywall helps reduce moisture absorption and provides a more durable wall system for Thunder Bay homes where spring snowmelt and seasonal humidity are common.

Fire-Rated Drywall For Suites & Commercial Buildings

Fire-rated drywall helps improve fire separation between attached garages, furnace rooms, basement apartments, multi-family properties, offices, and commercial spaces while meeting building code requirements where fire-resistant assemblies are specified.

Mould-Resistant Drywall For Restoration Projects

Following roof leaks, burst pipes, condensation, or water damage restoration, mould-resistant drywall provides added protection in moisture-prone areas while helping create healthier interior spaces for homes, cottages, and commercial properties.

Soundproof Drywall For Secondary Suites & Offices

Reduce noise transfer between basement apartments, bedrooms, home theatres, offices, meeting rooms, and multi-unit buildings with sound-control drywall systems designed to improve comfort and privacy.

Impact-Resistant Drywall For High-Traffic Areas

Designed for hallways, schools, healthcare facilities, retail spaces, warehouses, and busy commercial environments, impact-resistant drywall offers greater resistance to dents, scratches, and everyday wear than standard gypsum board.

Not Sure Which Drywall Is Right?

Whether you're renovating a home in County Fair, Academy Heights, or McKellar, finishing a basement suite in Summit, upgrading a cottage near Kakabeka Falls, or completing a commercial project in the Fort William Industrial Park, we'll recommend the most suitable drywall system based on your property's intended use, moisture exposure, durability requirements, and budget.

Drywall Restoration After Water Damage, Roof Leaks & Insurance Claims

  • Ice Dam Ceiling Damage

Thunder Bay's heavy snowfall and repeated freeze-thaw cycles can create ice dams that force water beneath shingles and into ceilings. We replace water-damaged drywall, eliminate stained ceiling sections, and restore a smooth, paint-ready finish after the roof leak has been resolved.

  • Seasonal Cottage Water Damage

Seasonal cottages left unheated over winter are more vulnerable to frozen pipes, unnoticed leaks, and moisture damage. We replace deteriorated drywall, repair ceilings and walls, and restore interiors before the property is reopened for the season.

  • Condensation & Indoor Moisture Damage

Long heating seasons combined with poor ventilation can lead to condensation around windows, exterior walls, and attic spaces. We replace moisture-damaged drywall and help restore affected areas once the source of excess humidity has been corrected.

  • Fire-Rated Drywall After Restoration

Following water, fire, or structural restoration, damaged fire-rated wall and ceiling assemblies often need to be rebuilt to maintain the required fire separation. We install new fire-rated drywall systems for garages, furnace rooms, commercial spaces, and multi-unit properties.

  • Commercial Property Restoration

Water damage in offices, retail spaces, schools, healthcare facilities, and industrial buildings often requires fast drywall replacement to reduce downtime. We coordinate restoration work to efficiently return commercial interiors to service.

  • Restoration Solutions Tailored To Thunder Bay Properties

Whether you're repairing a home in Birchwood Heights or Dawson Heights, restoring a seasonal property near Murillo, or completing a commercial insurance restoration along Arthur Street or the Red River Road corridor, we'll recommend the most practical drywall restoration solution based on the source of the damage, building requirements, and long-term performance.

Achieving A Smooth, Paint-Ready Finish For Renovation & Restoration Projects

1. Precise Taping & Joint Finishing

Professional joint taping, multiple coats of joint compound, and careful feathering create smooth, invisible seams that prevent joint lines from showing through primer and paint. Proper finishing is especially important when blending repairs into existing walls after renovations or restoration projects.

2. Smooth Walls With Level 4 & Level 5 Finishes

Whether your project requires a standard Level 4 finish or a premium Level 5 skim coat, we prepare walls for modern paints, feature lighting, and high-end interior finishes by minimizing surface imperfections and creating a uniform substrate.

3. Seamless Texture Matching & Ceiling Repairs

Matching smooth ceilings, knockdown textures, orange peel, or older plaster finishes requires experience and precision. We carefully blend repaired areas so patches become virtually undetectable after priming and painting.

4. Precision Sanding For Paint-Ready Surfaces

Professional sanding removes excess joint compound, eliminates ridges, and smooths transitions around joints, fasteners, and corner beads. Every surface is carefully inspected before priming to achieve a clean, consistent finish.

5. Clean Corners, Ceiling Lines & Drywall Details

Sharp inside corners, straight outside corner beads, crisp ceiling transitions, window returns, soffits, and bulkheads all contribute to a professional-looking interior. Careful detailing ensures every finished space looks clean, symmetrical, and ready for decorating.

6. Flawless Finishes For Thunder Bay Homes & Businesses

Whether you're restoring a character home in Fort William, renovating a property in Hyde Park, finishing a basement in Green Acres, or completing a commercial project near the Thunder Bay waterfront, we deliver smooth, paint-ready drywall finishes that blend seamlessly with existing interiors and stand up to everyday use.

How Much Does Drywall Cost in Thunder Bay?

Project Size

Larger drywall projects require more materials, labour, taping, mudding, and finishing than smaller repairs. A simple drywall patch costs significantly less than finishing a basement, restoring water-damaged ceilings, completing a commercial fit-out, or installing drywall throughout an entire home.

Type Of Drywall

Material selection affects both project cost and long-term performance. Standard drywall works well for most living areas, while moisture-resistant, mould-resistant, fire-rated, soundproof, and impact-resistant drywall are recommended for specialized residential, restoration, and commercial applications.

Water Damage & Restoration Requirements

Costs may increase when drywall has been affected by roof leaks, burst pipes, flooding, condensation, or mould. Removing damaged materials, drying the affected area, and replacing compromised drywall all influence the overall restoration cost.

Installation & Finishing Requirements

Pricing varies based on ceiling height, room layout, drywall thickness, Level 4 or Level 5 finishing, skim coating, texture matching, ceiling repairs, bulkheads, soffits, and the complexity of corners and architectural details.

Accessibility & Site Conditions

Upper floors, stairwells, occupied homes, cottages, finished basements, commercial buildings, and limited material access can increase labour requirements and influence overall project costs.

Residential vs Commercial Projects

Commercial projects often require steel stud framing, suspended ceilings, fire-rated wall assemblies, sound-rated partitions, impact-resistant drywall, and larger crews, which generally increase project costs compared to residential work.
