Specialist new build mastic for Stratfield Mortimer: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Frame joints opening as the plaster dries
- Gaps behind new kitchen upstands
- Sealant that never bonded to the surface
What we cannot put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Cracking that points to a structural problem
- Disputes or warranty claims with your builder
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
Joints and surfaces we work on
- Skirting & floors
- Kitchens
- Bathrooms & en suites
- Plot handovers
- Windows & doors
- Show homes
New build mastic in Stratfield Mortimer
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that’s what rushed new-build sealant normally lacks. We work on plot handovers, skirting & floors and bathrooms & en suites, and common reasons people get in touch are leaking shower tray seals in a new home and sealant work across a run of new homes.
In a village or hamlet like Stratfield Mortimer, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Every job is covered by a 12-month guarantee, wherever you are in West Berkshire.

Surface by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Signs you need new build mastic in Stratfield Mortimer
Sealant applied onto damp surfaces does not bond well. Site programmes don’t always leave time for joints to dry before the sealant goes on.
The problems people generally mention when they call are:
- Cracks appearing as a new home settles
- Frame joints opening as the plaster dries
- Untidy sealant flagged on a snagging list
- Cracked caulk along new skirting
If you’ve bought a new home near Mortimer station, the sealant around baths, showers and frames is worth checking in the first year or two.

How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Stratfield Mortimer, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
Getting a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.

Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Where a wall is exposed, as many are in small places like Stratfield Mortimer, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Can you match the sealant colour to my new kitchen or bathroom?

Can you work from my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we will do.
