New build mastic in Kemsley, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that is what rushed new-build sealant generally lacks. Common call-outs are for sealant that never bonded to the surface and gaps opening as the house dries out and settles, on bathrooms & en suites, skirting & floors and windows & doors.
For a new home in or near Kemsley, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
You get a one-year guarantee, the same in Kemsley as everywhere else we work.

When to call us in Kemsley
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 any of the following:
- Plot mastic for developers ahead of handover
- Sealant applied over dusty or wet surfaces
- Cracked sealant around new window and door frames
- Smeared, uneven beads picked up at snagging
If you’ve bought a new home near Kemsley station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- How much experience the applicator has
- Whether you can choose the colour
- How the surfaces are prepared before sealing
- What guarantee comes with the work
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The process
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. Parking around Kemsley is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions

What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Damaged fittings that need replacing
- Movement caused by a poorly fitted tray or bath
- Cracking that points to a structural problem
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Skirting & floors
- Show homes
- Windows & doors
- Bathrooms & en suites
- Kitchens
- Plot handovers
Why it’s worth doing now in Kemsley
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. In an older home around Kemsley, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- 20+ years of sealant experience
- ARBOMaster approved applicator
- Neat joints and a tidy finish
- Arbo and Everbuild products

Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Kemsley, along with the rest of our area.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
New build mastic in Kemsley: local notes
Kemsley is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
