What else we do in Fewcott
Do you need new build mastic in Fewcott?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
Look out for these signs:
- Joints pulling apart as timber shrinks
- Shower seals failing in the first year or two
- Gaps behind new kitchen upstands
- Plot mastic for developers ahead of handover
Around Fewcott, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- What insurance they hold
- Whether VAT is included
- Which sealant they’ll use, and why
Different surfaces, different methods
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Plumbing faults behind the sealant
- Disputes or warranty claims with your builder
- Damaged fittings that need replacing
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

Should I try it myself first?
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 doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Fewcott: your questions answered
Will you come out to Fewcott?
Yes. Fewcott is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Fewcott in your area for new build mastic?
Yes. We work across London and the South East, and Fewcott is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear price.
Should I go to my builder first?
Start with the builder if you are in the snagging or warranty period. If it isn’t resolved, we’ll cut it out and reseal it.
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 any work starts.
Should I try DIY first?
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.
How much does new build mastic cost in Fewcott?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Fewcott, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely 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.
- Each bead is tooled and the cure times explained.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
How to get a quote
We do not publish a price list, because every job is different. Instead, we send you a clear quote for your job. To arrange one, call 0345 464 0079 or send us an email.

Keeping the joints in good condition
So the new joints stay in good condition:
- Ventilate bathrooms well, especially in the first year
- Record problems with dated pictures
- Avoid scourers and strong chemicals on sealant
- Don’t seal over failed sealant yourself
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
