Our Process
Here's exactly what happens when you hire us for water damage drywall repair.
Assess and confirm dry
We check moisture levels with a meter. Patching wet drywall just traps moisture and grows mould — we don't do it. If it's not dry yet we'll tell you how to get there first.
Remove damaged material
All compromised drywall and insulation comes out. We cut back to clean, solid material so the repair has proper anchoring.
Flag anything we're not qualified for
Visible mould past surface staining, or structural damage, gets a specialist referral. We don't do remediation, but we work seamlessly after the remediator is done.
Install new drywall
New board cut to fit, screwed to studs or proper backing, taped and mudded with 3 coats. This is where rushed repairs fail — we don't rush mud drying.
Stain-block and texture
Shellac-based stain blocker so old water stains never bleed through your paint. Texture matched to surrounding wall or ceiling.
Prime and paint
Primer, then finish paint matched to the existing room. We photograph the completed work for your records or insurance claim.
Frequently Asked Questions
Should the drywall always be replaced after water damage?
Not always. Small surface stains where the drywall is still solid and dry can sometimes be cleaned, primed with a stain blocker, and repainted. But if the drywall is soft, sagging, swollen, or the paper is bubbled, it must come out. We test moisture with a meter and tell you honestly what needs replacing.
Do you handle mould?
No — and you should be wary of any drywall contractor who says yes. Mould remediation requires certified specialists, proper containment, and different insurance coverage. If we see visible mould past surface staining, we'll tell you, give you a referral, and come back to handle the drywall replacement once remediation is done.
Will the water stain come back through the paint?
Not if it's done right. Water stains contain tannins and contaminants that bleed through regular primer and paint. We use shellac-based or oil-based stain-blocking primer which seals the stain completely. Skipping this step is why DIY paint jobs show the stain again after a few weeks.
Do you work with insurance claims?
Yes. We can provide written quotes in a format adjusters accept, document the damage and our work with photos, and itemize our invoice so the claim is straightforward. We don't negotiate the claim on your behalf, but we make sure you have what you need to submit.
How much does water damage drywall repair cost?
Starts at $500 for small sections (a single ceiling stain with minor replacement). Larger jobs — a full ceiling section, multiple walls after a basement flood — typically run $1,000-$3,000+ depending on square footage, whether insulation needs replacement, and access difficulty. Quotes are always free and firm before work starts.
How long does it take?
Usually 2-4 days from start to paint finish, depending on size. Most of that time is drying — mud coats need 12-24 hours between each, and stain-blocking primer needs proper cure time. Rushing it is how repairs fail.
Can you come same-day for emergencies?
We can't offer 24/7 emergency response, but we do offer same-day quotes and same-week starts for water damage work. If you've had a flood, the priority is stopping the water and getting things dry — call us once that's handled and we'll get you scheduled fast.
