Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a small place like Gubblecote, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
Why book with us
- Quality sealants from Arbo and Everbuild
- We leave the area clean and tidy
- You choose the colour before work begins

About our new build mastic in Gubblecote
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We’re often asked to deal with joints pulling apart as timber shrinks and sealant that never bonded to the surface, on kitchens, windows & doors and plot handovers.
In a village or hamlet like Gubblecote, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

New homes and floors in Gubblecote
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Gubblecote, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Cheddington station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
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 does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Surface by surface
Plot handovers
Send us the schedule and any sealant specification. We seal bathrooms, kitchens, frames and floors as agreed.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Damaged fittings that need replacing
- A tray or bath that is not properly supported, until it’s fixed
- Plumbing faults behind the sealant
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.
Surfaces we seal
- Windows & doors
- Plot handovers
- Skirting & floors
- Bathrooms & en suites

How it works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Gubblecote, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- 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.
- Each bead is tooled and the cure times explained.
Before we arrive
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints

Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
How much does new build mastic cost in Gubblecote?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Why does sealant fail so quickly in new builds?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
