New build mastic in Hartford End, done properly
We work in new homes and on new-build sites across Hartford End. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. We work on bathrooms & en suites, windows & doors and skirting & floors, and common reasons people get in touch are cracks appearing as a new home settles and cracked sealant around new window and door frames.
Older homes in small places like Hartford End often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Every job is covered by a one-year guarantee, wherever you are in Essex.

Advice

Why it’s worth doing now in Hartford End
A hairline gap at a skirting can wait, but water getting through cannot. If you’re unsure which you have, phone 0345 464 0079 or email us with pictures and we’ll tell you. In a small place like Hartford End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What the job involves on each surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Do you need new build mastic in Hartford End?
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.
It’s worth asking for a quote if you see:
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
- Untidy sealant flagged on a snagging list
- New-build shower sealant that has already split
Whether the job is in Hartford End itself or nearby, the right material for each joint matters as much as a neat finish.
Before booking anyone
- What insurance they hold
- Whether all the old sealant comes out first
- Which colour the sealant will be
- Which sealant they’ll use, and why
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
