If you’re dealing with frame joints opening as the plaster dries and skirting joints opening in the first winter, we can help.

Your questions about new build mastic in Stonehill
I let a flat near Longcross station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Is Stonehill in your area for new build mastic?
Yes, Stonehill is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
How much does new build mastic cost in Stonehill?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or drop us an email and let us know what needs doing and where.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Do you work for developers?
Yes. We work through plots to your schedule ready for handover. Get in touch with the number of plots and the scope for a clear quote.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you’re covered. Once that is done, or if they won’t put it right, we will cut it out and reseal it.

How we quote for new build mastic
You’ll get a clear quote before work begins. It takes into account:
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- The number of rooms or windows
- Any mould that needs treating
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
Asking for a quote
Before you ask for a quote, have a think about:
- Photos by email, if that’s easy
- Where the property is
- Any previous sealing or DIY work
- What’s wrong with the joints now
For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. We will give you a clear quote before any work starts.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Look at the sealant regularly in the first couple of years
- Raise failed sealant with the developer while you are covered
- Don’t seal over failed sealant yourself
- Record problems with dated photos
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
Signs you need new build mastic in Stonehill
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry.
These are the problems we’re asked about most:
- Cracked sealant around new window and door frames
- Cracks appearing as a new home settles
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
In and around Stonehill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- Whether they seal over old material or remove it
- Which colour the sealant will be
- How the joint is cleaned and prepared
- What product goes in the joint
Different surfaces, different methods
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing.
The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Stonehill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
Ask for a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or send us an email.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
