About our new build mastic in Lampton
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks rather than sitting on a layer of grit. We work on windows & doors, kitchens and plot handovers, and common reasons people get in touch are kitchen sealant that has pulled off the wall and gaps opening as the house dries out and settles.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement, in Lampton as anywhere.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Can parking be tricky for a visit in Lampton?

Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

New build mastic in Lampton: local notes
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. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
For new homes near Hounslow station, it’s worth checking the sealant early, while snags are still fresh.

How we quote for new build mastic
For a quick quote, just ask. The main things that affect it are:
- The type of sealant required
- Any working-time requirements on site
- Whether there’s mould to deal with
- The number and length of the joints
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear price before any work starts.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- Whether it has been sealed before
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or email us.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Raise failed sealant with the developer while you are covered
- Act quickly if a seal starts to leak
- Wait for the cure time before using a resealed shower
- Record problems with dated pictures
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
How the visit works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. In Lampton, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
Getting a quote
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
Related advice
Landlords, agents and businesses in Lampton
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
Common problems we fix in Lampton
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Most people get in touch when they notice something like this:
- Sealant that never bonded to the surface
- Worktop and upstand sealant coming away
- Gaps between new skirting and floors
- Second-fix sealing on new plots
Lampton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
