What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It normally takes a few hours in a single home. Somewhere like Headley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- 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.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints

New build mastic for homes and businesses in Headley
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on windows & doors, plot handovers and kitchens, and the jobs we see most are internal frame sealant that has split and gaps opening as the house dries out and settles.
In a village or hamlet like Headley, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Big or small, you get the same 12-month guarantee.

Aftercare tips
A little care helps the new joints last. We recommend:
- Get a leaking seal dealt with straight away
- Avoid scourers and strong chemicals on sealant
- Resist patching a failed seal with a tube from the DIY shop
- Keep water off fresh sealant until it has cured
Don’t stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
Signs you need new build mastic in Headley
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
If you can see any of these, it’s time to have the joints looked at:
- Skirting joints opening in the first winter
- Plot mastic for developers ahead of handover
- Beads laid onto grit and dust from the build
- Leaking shower tray seals in a new home
Around Headley, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- When the joint can take water or movement
- Is VAT in the price?
- What happens if the job turns out different
- Is the old sealant removed completely?
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
New build mastic in Headley: local notes

How we quote for new build mastic
Every job gets its own quote. These are the things that affect it:
- How easy the joints are to reach
- The number and length of the joints
- The type of sealant required
- How many rooms, windows or areas are involved
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

Your questions about new build mastic in Headley
Do you work for landlords with property near Tadworth station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Do you cover smaller places like Headley?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Will you just run a new bead over the existing one?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Different surfaces, different methods
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Deciding who is responsible under a builder’s warranty
- Cracked trays, tiles or worktops
- Baths and trays that move too much for sealant to cope with
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
