New build mastic in Newbury Park
We work in new homes and on new-build sites across Newbury Park. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. If you have leaking shower tray seals in a new home and internal frame sealant that has split, we can put it right.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

FAQs for Newbury Park
I let a flat near Seven Kings station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Is parking an issue for new build mastic in Newbury Park?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you cover Newbury Park?
We do. Our applicators work in Newbury Park.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. 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.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Preparing for the visit
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Advice
What affects the quote in Newbury Park
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The type of sealant required
- When we can work, for business premises
- Mould in or behind the old joints
- The number and length of the joints
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.
What we need to know
Before you ask for a quote, have a think about:
- The address or postcode of the job
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
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’ll talk you through the work and give you a clear price.

Joints and finishes in Newbury Park homes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Seven Kings station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
