About our new build mastic in Chelwood Common
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you are still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on skirting & floors, kitchens and windows & doors, and the jobs we see most are cracked sealant around new window and door frames and leaking shower tray seals in a new home.
Around Chelwood Common, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job comes with our 12-month guarantee, wherever you are in West Sussex.

Should I try it myself first?
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. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we are called out for in Chelwood Common
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
The problems people usually mention when they call are:
- Shower seals failing in the first year or two
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
- Sealant applied over dusty or wet surfaces
Whether the job is in Chelwood Common itself or nearby, the right material for each joint matters as much as a neat finish.

What affects the quote in Chelwood Common
Some jobs are bigger than they look, and some smaller. The main factors:
- Access and height
- Which sealant suits the joint
- Whether there’s mould to deal with
- Any working-time requirements on site
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
Helping us quote
To make quoting easier, let us know:
- How we’d reach the joints
- Photos by email, if that is easy
- The rough size of the job
- If someone has resealed it before
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
Why act early in Chelwood Common
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Where a wall is exposed, as many are in small places like Chelwood Common, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Common questions in Chelwood Common
What guarantee comes with new build mastic in Chelwood Common?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Chelwood Common in your area for new build mastic?
Yes. We work across London and the South East, and Chelwood Common is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Who should fix failed sealant in a new build?
Report it to the builder first while you are covered. Once that’s done, or if they won’t put it right, we will cut it out and reseal it.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
How long will you be here?
Typically it takes a few hours in a single home. Larger jobs naturally take longer, and we’ll tell you how long to expect.
The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours in a single home, and the area is left clean.
