South Earlswood New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for householders, landlords and businesses in South Earlswood. Fully insured, ARBOMaster approved and guaranteed for a year.
- Sealant that never bonded to the surface
- Cracks appearing as a new home settles
- Smeared, uneven beads picked up at snagging
Why act early in South Earlswood
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Where a wall is exposed, as many are in small places like South Earlswood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Why book with us
- Any old sealant cut out fully, not covered over
- White, clear, grey or coloured to suit, where the product allows
- More than 20 years in sealant work
- Experience in homes, commercial sites and hotels

New build mastic for homes and businesses in South Earlswood
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks. If you have skirting joints opening in the first winter and leaking shower tray seals in a new home, we can put it right, whatever the surface.
Somewhere as small as South Earlswood, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

How the job changes by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
DIY sealant or a professional job?
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 doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like South Earlswood, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
Getting a quote
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, call 0345 464 0079 or email us.
Advice
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Do not wait for the house to settle if water is getting through
- Wait for the cure time before using a resealed shower
- Look at the sealant regularly in the first couple of years
- Ventilate bathrooms well, especially in the first year
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.

Your questions about new build mastic in South Earlswood
Is South Earlswood in your area for new build mastic?
Yes. We work across London and the South East, and South Earlswood is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Will you come out to South Earlswood?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
How long will you be here?
That depends on the amount of work, but as a guide it takes anything from a few hours to several days, depending on the number of plots. We’ll give you a better idea when we quote.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
