Common problems we fix in Chessington
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry.
People usually contact us after spotting something like this:
- Plot mastic for developers ahead of handover
- Gaps between new skirting and floors
- Kitchen sealant that has pulled off the wall
- New-build shower sealant that has already split
For new homes near Chessington North station, it’s worth checking the sealant early, while snags are still fresh.

How we handle new build mastic in Chessington
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We work on bathrooms & en suites, show homes and kitchens, and people most often call us about cracked caulk along new skirting and joints pulling apart as timber shrinks.
New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
There’s a 12-month guarantee on every job.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Act quickly if a seal starts to leak
- Clean sealant with mild detergent, not abrasives
- Avoid running a DIY bead over the old one
- Check bath and shower seals every few months as the house settles
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.

How much does new build mastic cost in Chessington?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
Do you have insurance?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Will you just run a new bead over the existing one?
No. Fresh silicone does not stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
How the job changes by surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
How it works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on the number of plots in most cases. In Chessington, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why act early in Chessington
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Chessington, the repair is bigger than a sealant job.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
