Little Horwood New Build Mastic
Our applicators work in Little Horwood on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Cracked sealant around new window and door frames
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep pictures and emails about snagging items
- Raise failed sealant with the developer while you are covered
- Get a leaking seal dealt with right away
- Wait for the cure time before using a resealed shower
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
New build mastic for homes and businesses in Little Horwood
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on bathrooms & en suites, windows & doors and kitchens, and the jobs we see most are gaps opening as the house dries out and settles and untidy sealant flagged on a snagging list.
Around Little Horwood, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Big or small, it’s backed by our one-year guarantee in Little Horwood and across Milton Keynes.

Advice
Why it’s worth doing now in Little Horwood
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. In a small place like Little Horwood, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.
