New build mastic in Claygate Cross

We work in new homes and on new-build sites across Claygate Cross. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. Typical jobs include skirting joints opening in the first winter and cracks appearing as a new home settles, across plot handovers, bathrooms & en suites and windows & doors.

Somewhere as small as Claygate Cross, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

A one-year guarantee comes as standard, so you are covered after we have gone.

Leave it or put it right?

The builder is usually 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. Around Claygate Cross, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Do you need new build mastic in Claygate Cross?

Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.

It’s worth asking for a quote if you see:

  • Sealant applied over dusty or wet surfaces
  • Shower seals failing in the first year or two
  • Gaps behind new kitchen upstands
  • Cracks appearing as a new home settles

If you’ve bought a new home near Borough Green & Wrotham station, the sealant around baths, showers and frames is worth checking in the first year or two.

10 questions to ask before you book

DIY sealant or a professional job?

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.

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Landlord and commercial work in Claygate Cross

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.

What we do, step by step

At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours in a single home, depending on the size of the job. In a small place like Claygate Cross, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by going through the snagging items or plot schedule with you.
  2. Every bit of the old builder’s sealant is cut out down to clean surfaces.
  3. We clean out the dust and grit left from the build.
  4. We prime where needed and apply a sealant suited to each joint.
  5. Each bead is tooled and the cure times explained.

Before we arrive

  • For business premises, tell us about site rules or sign-in

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Open a window or run the fan after bathing
  • Avoid scourers and strong chemicals on sealant
  • Keep water off fresh sealant until it has cured
  • Keep pictures and emails about snagging items

Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day.

The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.

What affects the cost of new build mastic

Your quote is based on your job. We take into account:

  • How easy the joints are to reach

  • Whether it’s a home or a business
  • What the problem is, such as mould, gaps, leaks or cracking

Questions from Claygate Cross

Do you cover smaller places like Claygate Cross?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is Claygate Cross in your area for new build mastic?

Yes, Claygate Cross is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.

Can landlords and businesses book you?

Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.

Can you work from my snagging list?

Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we will do.

My new home is still under warranty. Should I contact you?

Start with the builder if you’re in the snagging or warranty period. Once that’s done, or if they won’t put it right, we’ll cut it out and reseal it.

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.

Do the sealants smell?

That depends on the sealant. Some products have a noticeable smell, others very little.

Do you do commercial work?

Yes. Hotels, offices and other businesses use us and we’re fully insured.
