A burst supply line, an overflowing tub, or a storm surge under the back door doesn't wait for business hours, and neither do we. Our Grantham-based teams arrive with truck-mount extractors, moisture meters, and drying gear staged and ready to go.
We built our Grantham branch after hearing the same complaint over and over from Grantham, NH property owners — the "24/7" number that never actually answers. Every technician on our Grantham roster is a Hirex Water Damage employee, not a gig-app contractor pulled from a random directory.
Our senior technicians are IICRC-certified and have worked everything from a clean supply-line break to a full sewage backup, so Water Damage Repair in Grantham isn't a side service we tacked on — it's the reason the company exists. We carry full general liability coverage and are licensed to operate throughout Grantham, NH, so you're protected from the moment our truck pulls into the driveway.
We keep a stocked warehouse inside Grantham, NH so equipment never has to be trucked in from another region, which is the difference between a 45-minute arrival and a next-day one.
Ask any Grantham property manager who has dealt with a burst supply line at 3am — the difference between a crew that shows up ready and one still loading a truck at the shop is measured in gallons of water soaking into your subfloor. That's the gap Hirex Water Damage was built to close, one Grantham call at a time.
Not every leak announces itself with a flooded floor. A lot of the worst damage we see in Grantham started small and got ignored for weeks. Here's what tells us a property needs professional attention rather than a mop and a fan:
If any of that sounds familiar, don't wait for it to get worse — call our Grantham line and we'll tell you honestly whether it's a same-day emergency or something we can schedule.
We size the Grantham response to the actual damage — a single-room extraction gets a two-person crew, a commercial loss gets the full fleet — nothing gets a cookie-cutter response.
Our Grantham units run truck-mount extraction pumps that pull thousands of gallons per hour, cutting standing-water time from days to hours. Every extraction job includes moisture mapping so we know exactly which materials are still holding water once the visible flooding is gone.
Once water is out, we bring in commercial air movers and LGR dehumidifiers, positioned using psychrometric readings rather than guesswork, with daily drying logs so you can see the numbers improving, not just take our word for it.
For families in Grantham, this covers flood-cut drywall removal, subfloor evaluation, and packing out salvageable belongings for cleaning, with clear photo documentation at every stage for your insurance claim.
For commercial Grantham accounts, we assign a project lead, run crews after normal hours to reduce downtime, and bring equipment sized to the actual footprint — we know a flooded lobby or a leaking unit above tenants below has to move fast.
When a Grantham job involves sewage backup, our team suits up in full PPE, applies EPA-registered antimicrobials, and safely disposes of porous materials that can't be saved.
We apply antimicrobial treatment during every Grantham drying job specifically to head off mold before it starts, and we'll flag any area that needs deeper remediation.
You get a written estimate before any equipment runs, not a mystery total handed to you after the fact.
Because our equipment cache sits inside Grantham, NH, most Grantham calls see a technician on-site in under 60 minutes.
We photograph and log every step specifically so your claim moves faster and you're not the one arguing with the insurance company.
If moisture readings aren't where they should be at the end of the job, we come back and keep drying at no extra charge.
A short call with our Grantham dispatcher tells us whether this is a one-room job or a multi-crew response before anyone drives out.
A licensed technician heads to your Grantham address with extraction and drying equipment already loaded.
Standing water comes out first; drying equipment gets placed only after we've mapped exactly where moisture is hiding.
We don't close the file until the numbers confirm the structure is dry, and you leave with full photo and moisture documentation.
We measure moisture with instruments, not guesswork, and we won't sign off on a Grantham job until those readings match the dry standard for the materials involved. If a callback shows lingering moisture within 30 days of a completed job, we return and correct it at no additional charge.
That's not a marketing line — it's written into every Grantham work order we issue. A repeat visit under this guarantee doesn't mean starting over — we pull the original moisture logs and pick up exactly where the last visit left off.

If it's safe, shut off the water source, move electronics and valuables away from the affected area, and avoid the space if standing water is near outlets.
