Market town and logistics hub
Daventry sits on high ground between the M1 and the A5, and its work splits clearly in two.
In town, the 1960s and 70s expansion estates such as Southbrook, Ashby Fields and Grange have homes that are on their second or third set of windows, plus newer streets at Middlemore and Monksmoor. Window mastic, bathroom resealing and kitchen sealant make up most domestic calls.
A few miles away, the Daventry International Rail Freight Terminal and the business parks around it have some of the largest warehouses in the country. Their floor joints, dock levellers, cladding and movement joints all need a sealant contractor who understands large commercial schedules.
The old Borough Hill transmitter site, the canal reservoir and the town centre around Sheaf Street give Daventry a character of its own. Many shopfronts in the Market Place have tall single-glazed and replacement frames whose perimeter joints are now brittle.

Concrete joint sealing for large warehouses
Warehouse floors are cut into bays, and every saw-cut and construction joint needs sealant that can take wheel loads. When it fails, the joint edges spall and the floor gets rougher with every pallet truck.
We clean the joints back to sound concrete, prime where required and reseal with a hard-wearing polyurethane, or a polysulphide sealant in fuel and chemical areas. We can quote from a floor plan and work in phases.

Domestic mastic and silicone in Daventry
For homeowners and landlords we cut out failed silicone around baths and showers, reseal kitchen worktops, and renew window and door mastic so the frames are weathertight again.
Every domestic job is priced up front, and we explain what sealant we are using and why.
If you are looking for a mastic man near me in Daventry, we also cover new-build plot mastic and snagging at Monksmoor, re-mastic uPVC windows to stop draughts, reseal wet rooms and en-suites with anti-mould sanitary silicone, and seal expansion joints with backer rod and low-modulus, colour-matched sealant. On listed buildings in the old town we use non-staining products. We are sealant specialists across Northamptonshire, and every Daventry shower resealing or bathroom resealing job gets the same care as a big contract.

Daventry sealant questions
Do you work at DIRFT and Daventry business parks?
Yes. We seal warehouse floor joints, movement joints, cladding and dock areas for owners, tenants and main contractors, with RAMS and phased working.
What is the cost of a mastic man in Daventry?
Domestic resealing is priced per job from photos. Commercial work is priced per metre from a joint schedule or floor plan. Either way you get a clear price before work starts.
Which sealant is best for warehouse floor joints?
Usually a hard-wearing polyurethane sealant. Where there is fuel or chemical exposure, a polysulphide sealant is often the better choice.
Can you reseal my bathroom in Daventry?
Yes. We remove the old silicone, treat any mould, and reseal with a sanitary silicone designed for wet areas.
