- Cracked caulk along new skirting
- Joints pulling apart as timber shrinks
- Sealant that never bonded to the surface
How we handle new build mastic in West Hill
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. Common call-outs are for plot mastic for developers ahead of handover and untidy sealant flagged on a snagging list, on skirting & floors, show homes and bathrooms & en suites.
Where new homes go up in smaller places like West Hill, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
All of our work is guaranteed for twelve months.

Your questions about new build mastic in West Hill
Can you do new build mastic in West Hill?
Yes, West Hill is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Do you cover smaller places like West Hill?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
What does new build mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is the work guaranteed?
Yes. All our work carries our 12-month guarantee.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but sealant comes in other colours too. We choose one to suit the room.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Why act early in West Hill
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. Homes in smaller places like West Hill can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

How we quote for new build mastic
Jobs vary more than people expect. The main factors:
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- The number of rooms or windows
- Any working-time requirements on site
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
Asking for a quote
When you contact us, it’s useful to know:
- What’s wrong with the joints now
- The rough size of the job
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or email us.
Surface by surface
Show homes
We seal show-home bathrooms, kitchens and frames to a tidy standard. We’ll plan around viewing times.
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.
How it works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. For a job in West Hill, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit

Advice
Looking after it afterwards
So the new joints stay in good condition:
- Use the extractor fan every time you shower
- Keep water off fresh sealant until it has cured
- Put sealant faults on your snagging list early
- Act quickly if a seal starts to leak
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.

West Hill is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging.
