New build mastic in Staines-upon-Thames, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you’re dealing with shower seals failing in the first year or two and plot mastic for developers ahead of handover, we can put it right, whatever the surface.
Homes around Staines-upon-Thames move a little with the seasons, and skirting and floor joints show it first. Those joints need a flexible sealant, as rigid filler soon cracks out.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

The process
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours in a single home for a typical job. In Staines-upon-Thames, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a family home in Staines-upon-Thames, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Left alone, that means rot, damp and a bigger repair.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What affects the cost of new build mastic
There’s no set price list. The quote depends on:

The problems people generally mention when they call include:
- Cracked sealant around new window and door frames
- Leaking shower tray seals in a new home
- Joints pulling apart as timber shrinks
- Beads laid onto grit and dust from the build
For new homes near Staines station, it’s worth checking the sealant early, while snags are still fresh.

Can you help a landlord with a rental near Staines station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
What does new build mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Will you just run a new bead over the existing one?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
