New build mastic near Selsfield Common

New build mastic in Selsfield Common

Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We are often asked to deal with beads laid onto grit and dust from the build and gaps opening as the house dries out and settles, on skirting & floors, windows & doors and bathrooms & en suites.

Older homes in small places like Selsfield Common often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

There’s a 12-month guarantee on every job, whatever its size.

For landlords and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Surface by surface

Bathrooms and en suites

Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.

Windows and doors

The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.

Selsfield Common: your questions answered

Is Selsfield Common in your area for new build mastic?

Yes. Our work covers London and the South East, and Selsfield Common is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.

Is Selsfield Common within the area you cover?

Yes, Selsfield Common is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is it worth resealing while the house is still settling?

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?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

Do you work for developers?

Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.

Can landlords and businesses book you?

Yes, we do. Domestic, commercial and hotel work are all part of what we do.

Do the sealants smell?

There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

How long does the job take?

A typical job takes a few hours in a single home. We will confirm how long when we quote.

Can I do it myself?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

A careful DIYer can reseal a simple joint, 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.

How it works

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for most snagging lists, longer for a run of plots. In a small place like Selsfield Common, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each joint is checked for movement before work begins.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  4. Baths are filled with water, then the new sealant is applied.
  5. The finished joints are checked and the cure times given.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Move anything stored near the joints
  • Plan for the work area to be out of bounds to pets and children

Aftercare tips

So the new joints stay in good condition:

  • Get a leaking seal dealt with straight away
  • Clean sealant with mild detergent, not abrasives
  • Wait for the cure time before using a resealed shower
  • Photograph failed sealant before it’s redone

Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.

If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

Honest limits

Sealant isn’t the answer to every problem, and we’ll tell you before we start. It will not solve:

  • Broken tiles or a split tray
  • Cracking that points to a structural problem
  • Movement caused by a poorly fitted tray or bath

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

Surfaces we seal

  • Plot handovers
  • Kitchens
  • Windows & doors
  • Bathrooms & en suites
  • Show homes
  • Skirting & floors

Why deal with it now?

Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time. Older cottages and farmhouses around Selsfield Common can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
