Lanham property owners dealing with water damage have one smart move: call COS Water Damage Restoration and get a local crew on site within the hour. COS Water Damage Restoration's Lanham-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Positioned in Lanham for fast local response every time.
Every technician holds current WRT certification — the industry standard.
No hidden fees, no last-minute line items.
Works with all major MD insurers.
We've handled everything from flash-flood basement extractions in Lanham's older neighborhoods to multi-floor commercial water events in newer construction, and every job has reinforced the same core truth: speed and expertise make the difference between a manageable repair and a catastrophic rebuild.
We bring enterprise-grade extraction and drying equipment to every Lanham job — not the rental-store grade equipment that leaves moisture in wall cavities and under flooring that causes mold weeks after the job was supposedly done.
COS Water Damage Restoration has earned the trust of Lanham homeowners, landlords, property managers, and commercial facility owners because we consistently do what we say we'll do: we arrive when we say we'll arrive, we provide the estimate we quoted, we complete the documentation we promised, and we stand behind the work with a written satisfaction guarantee.

Every service listed below is available 24/7 in Lanham — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
In Lanham, our emergency extraction crews maintain ready-to-deploy status every hour of every day — because the fastest response to flooding directly determines how much of your property can be saved. Lanham's Water Damage Repair emergency calls include everything from clean water supply line failures to contaminated sewage backflows, and our crews are trained and equipped for every category of water damage — with the right PPE, containment protocols, and extraction methods for each situation.
Our residential restoration teams in Lanham are experienced across the full range of home types found in the area — older homes with original hardwood and plaster, newer construction with engineered materials and finished basements, and everything in between. Daily check-ins from your project manager keep you informed throughout the drying cycle, and reconstruction doesn't begin until documented moisture readings confirm every structural assembly has reached target levels.
We work in occupied buildings, schedule around your operating hours when it's possible to do so safely, and produce the detailed loss documentation that commercial insurance adjusters require — all as standard practice, not a premium option. Our Lanham commercial team has experience with office buildings, multi-tenant retail spaces, restaurants and hospitality properties, warehouses and light industrial facilities, medical and professional offices, and multi-family residential properties.
Mold is the almost-inevitable consequence of water damage that wasn't addressed quickly or completely — and in Lanham's climate, wet building materials can support mold growth in as little as 24 to 48 hours after initial exposure. Post-remediation air quality testing provides objective confirmation that the remediation was successful, and the written clearance report we issue becomes part of your property's maintenance record.
Building new drywall or flooring over materials that are still holding excess moisture leads to cracking, warping, fastener failure, paint peeling, and eventually mold growth — which is why our Lanham drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. We deploy industrial LGR dehumidifiers and high-velocity air movers in a calculated configuration based on the square footage, material types, and psychrometric conditions specific to your Lanham property — not a one-size-fits-all equipment drop.
COS Water Damage Restoration takes the second challenge entirely off your hands — from the first notice of loss through final settlement — so you can focus on your family and your recovery rather than on paperwork, phone calls, and adjuster negotiations. Our approach to insurance coordination in Lanham is built on the principle that your policy was paid to cover a genuine loss, and our job is to make sure it pays what it's supposed to.



Don't wait to call — our Lanham emergency line is live 24/7 and help is closer than you think.
📞 Call +1-844-499-0972 — Lanham Emergency LineWhen water damage hits in Lanham, the decision you make in the first 30 minutes — who you call and how fast they show up — will define the entire scope and cost of your restoration experience.
When you call COS Water Damage Restoration in Lanham, the crew that shows up actually works here.
Speed of response is the single most controllable factor in limiting water damage costs — and we've optimized our Lanham operation around it.
Our Xactimate-based estimates are formatted the way your MD insurance carrier expects to receive them, which means no disputes and faster claim processing.
Your Lanham home or business deserves the professionalism that certification represents.
Lanham jobs get industrial LGR dehumidifiers, truck-mounted extraction, thermal imaging cameras, and moisture mapping arrays — not residential-grade rental equipment.
Our Lanham claim team knows the carriers serving this market, the documentation those carriers require, and how to build a file that moves through underwriting quickly and pays out what you're owed.
Five-star reviews are earned, not purchased — and they reflect what happens when every technician takes personal pride in the outcome of every job.
One contact, complete accountability, from start to finish.
Our process eliminates the guesswork and the anxiety of not knowing what comes next — because you deserve to know exactly what your restoration team is doing and why at every step.
Your dispatcher gathers the essential information, identifies the closest available Lanham crew, and dispatches them immediately — all within the first few minutes of your call.
You receive a clear verbal briefing and a written estimate scope before any work begins.
Contaminated water scenarios activate full containment protocols — antimicrobial pre-treatment, barrier installation, and regulated disposal procedures to protect your household from cross-contamination.
A calculated drying plan is implemented immediately following extraction — air movers and dehumidifiers placed based on psychrometric data specific to your Lanham property's materials and conditions.
Pre-existing or emerging mold growth is addressed by our IICRC-certified remediation specialists with containment, HEPA air scrubbing, material removal, and clearance testing.
The final walkthrough is conducted with you personally, confirming satisfaction with every element before we close out the job and hand you your warranty documentation.
When a restoration company sends a crew to your Lanham property who has never worked in the area, the difference in performance is real — and it shows up in ways that matter: slower navigation to your address, unfamiliarity with local building code requirements that affect how drying and reconstruction are approached, no relationship with local supply vendors that allows materials to be sourced quickly, and no reputation to protect within the community they're serving.
Lanham's mix of housing stock — from older historic homes to newer construction developments — presents a range of material and structural challenges that our crews encounter regularly.
That local context makes our assessments more accurate, our response timelines more reliable, and our client communication more informed.
Water damage restoration costs in Lanham vary based on several factors: the volume of water, the category of water (clean vs. contaminated), the materials affected, the square footage involved, and the extent of mold risk. Most residential water damage events in Lanham fall within a range that homeowner insurance covers significantly, which is why our insurance coordination service is so valuable — we help make sure your policy pays what it should so your out-of-pocket is minimal. Call +1-844-499-0972 for a free on-site estimate with no obligation to proceed — we'll give you a clear picture of scope and cost before you commit to anything.
COS Water Damage Restoration's goal is to make the worst part of dealing with water damage — that initial frantic hour — as manageable as possible, and we start doing that the moment you pick up the phone.

Real reviews from Lanham, MD property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"We had a washing machine overflow that soaked the laundry room and wicked into the adjacent bedroom overnight before we noticed it. I found it in the morning and called COS Water Damage Restoration immediately. Their crew was at my Lanham house in 55 minutes — which was remarkable given that I called at 7 a.m. on a Saturday. They found moisture under the bedroom baseboard that I never would have caught, set up drying equipment that ran for five days, and the project manager called me with readings every morning. No mold, no lingering smell, and the claim went through without a single request for additional documentation. Absolute professionals."
"The burst pipe situation in our Lanham rental unit was a nightmare — the tenants called me at midnight, the unit was partially flooded, and I had no idea how bad it was. COS Water Damage Restoration's crew was on site before I could even get there myself. By the time I arrived, extraction was underway and the project manager was already walking through the damage assessment with photos. I had a full scope and estimate in my email before 2 a.m. The restoration was completed on schedule, within the estimated cost, and my tenant was back in the unit within two weeks. Outstanding."
"Mold found during the renovation of our Lanham home led us to COS Water Damage Restoration for remediation. The discovery was stressful — we didn't know how extensive it was or what it meant for the timeline of our project. The COS Water Damage Restoration team came in, assessed it thoroughly, explained exactly what they found and what the IICRC-compliant remediation process looked like, and completed the job on time. The post-remediation air testing came back clear, the report they provided satisfied our contractor and our insurer, and we were back on schedule within a week. Professional from beginning to end."
