New build mastic in Ash Vale
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. Typical jobs include skirting joints opening in the first winter and second-fix sealing on new plots, across windows & doors, bathrooms & en suites and plot handovers.
Homes around Ash Vale range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
Each job carries a 12-month guarantee.

What the job involves on each surface
Show homes
We seal show-home bathrooms, kitchens and frames to a tidy standard. We will plan around viewing times.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Why it’s worth doing now in Ash Vale
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Around Ash Vale, 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.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Do you need new build mastic in Ash Vale?
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
Keep an eye out for any of the following:
- Shower seals failing in the first year or two
- Sealant that never bonded to the surface
- Gaps opening as the house dries out and settles
- Cracked caulk along new skirting
If you’ve bought a new home near Ash Vale station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- Whether VAT is included
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- Who does the work, and how experienced they are

Questions from Ash Vale
Do you cover Ash Vale for new build mastic?
Yes. Our work covers London and the South East, and Ash Vale is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Is Ash Vale within the area you cover?

Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do.
Do you work through snagging lists?
Yes. Send it with photos and we will quote for the sealant items. If something isn’t sealant, we’ll say so.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
How it works
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 in a single home for a typical job. For a job in Ash Vale, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
