Bassett New Build Mastic
Our applicators work in Bassett on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Plot mastic for developers ahead of handover
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
How we handle new build mastic in Bassett
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on bathrooms & en suites, windows & doors and show homes, and common reasons people get in touch are frame joints opening as the plaster dries and new-build shower sealant that has already split.
In smaller places like Bassett, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What happens on the day
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for most snagging lists, longer for a run of plots. A visit to Bassett is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed

What else we do in Bassett
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Plumbing faults behind the sealant
- Disputes or warranty claims with your builder
- Cracking that points to a structural problem
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

What information do you need?

When is the best time to reseal in a new build?

What does new build mastic cost?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or drop us an email with a short description of the job.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Why deal with it now?
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a smaller place like Bassett, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
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.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Photograph failed sealant before it’s redone
- Wipe joints with warm soapy water
- Put sealant faults on your snagging list early
- Get a leaking seal dealt with straight away
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
Joints and finishes in Bassett homes
Bassett is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Bassett, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Swaythling station, the sealant around baths, showers and frames is worth checking in the first year or two.
