New build mastic in Wash Common
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. If you’re dealing with shower seals failing in the first year or two and joints pulling apart as timber shrinks, we can put it right, on bathrooms & en suites, skirting & floors and plot handovers alike.
Homes around Wash Common range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
Each job carries a 12-month guarantee.

What we do, step by step
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. In a smaller place like Wash Common, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Clear the area around the work

Wash Common questions
Do you cover smaller places like Wash Common?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Wash Common in your area for new build mastic?
Yes. We work across London and the South East, and Wash Common is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.
Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
My new home is still under warranty. Should I contact you?
Your builder, if you are still in their snagging or warranty period. If that doesn’t work out, we are happy to quote.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Signs you need new build mastic in Wash Common
Sealant applied onto damp surfaces does not bond well. On a busy site, joints aren’t always given time to dry.
Keep an eye out for these signs:
- Gaps between new skirting and floors
- Worktop and upstand sealant coming away
- Frame joints opening as the plaster dries
- Shower seals failing in the first year or two
Around Wash Common, as everywhere, new build mastic is only as good as the preparation behind it.

Why it’s worth doing now in Wash Common
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Wash Common, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

How the job changes by surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
