Is Copford within the area you cover?

New build mastic for homes and businesses in Copford
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. If you have messy sealant that spoils new finishes and plot mastic for developers ahead of handover, we can help.
Somewhere as small as Copford, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.

We quote each job on its own. Simply call 0345 464 0079 or email us and describe the job, and pictures are welcome.
New build mastic in Copford: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Signs you need new build mastic in Copford
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant around new window and door frames
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
- Cracked caulk along new skirting
In and around Copford, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- Whether they’re fully insured
- How long the guarantee is
- What happens if the job turns out different
- Who turns up on the day
Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Where a wall is exposed, as many are in small places like Copford, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- We agree the colour with you first
- A choice of colours where the product allows
- Arbo and Everbuild products
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Cracked trays, tiles or worktops
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Plot handovers
- Bathrooms & en suites
- Skirting & floors
- Kitchens
- Windows & doors
- Show homes
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
