About our new build mastic in Ashmore Green
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on kitchens, plot handovers and skirting & floors, and common reasons people get in touch are kitchen sealant that has pulled off the wall and untidy sealant flagged on a snagging list.
For a small place like Ashmore Green, the journey and access are planned in advance, and the work itself is the same as on any site.
You get a 12-month guarantee, the same in Ashmore Green as everywhere else we work.

What affects the cost of new build mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- The amount of work
Doing several joints on one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.

- Whether it’s a home or a business
- Whether it has been sealed before

Signs you need new build mastic in Ashmore Green
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Most people get in touch when they notice something like this:
- Sealant work across a run of new homes
- Cracked sealant around new window and door frames
- Sealant applied over dusty or wet surfaces
- Gaps behind new kitchen upstands
In and around Ashmore Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- How much experience the applicator has
- Is VAT in the price?

How it works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job normally takes a few hours in a single home, and we explain the cure time before we leave. Somewhere as small as Ashmore Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

Different surfaces, different methods
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there, food-safe where it’s needed.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Landlord and commercial work in Ashmore Green
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We also work for property managers and facilities teams in Ashmore Green and across West Berkshire. We can quote a run of properties together.
Common questions in Ashmore Green
Do you cover Ashmore Green for new build mastic?
Yes. We work across London and the South East, and Ashmore Green is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Newbury Racecourse station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common. Poor preparation at handover adds to it.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before work begins.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. If that doesn’t work out, we’re happy to quote.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Why act early in Ashmore Green
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times to plan around. Where a wall is exposed, as many are in small places like Ashmore Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
