New Build Mastic in Woolmer Hill
Problem with your new-build sealant joints in Woolmer Hill? We cut out the old, prepare the joints and apply the right sealant.

New build mastic in Woolmer Hill
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks rather than sitting on a layer of grit. We work on bathrooms & en suites, windows & doors and show homes, and common reasons people get in touch are skirting joints opening in the first winter and joints pulling apart as timber shrinks.
Around Woolmer Hill, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Our work is backed for twelve months, in Woolmer Hill and everywhere else we cover.

Different surfaces, different methods
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out with baths filled first.
What happens if it’s left?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Around Woolmer Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is usually more efficient than separate visits. We’ll send you a clear quote for the lot.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Get a leaking seal dealt with right away
- Report sealant problems to your builder during the snagging period
- Resist patching a failed seal with a tube from the DIY shop
- Keep pictures and emails about snagging items
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Movement caused by a poorly fitted tray or bath
- Damaged fittings that need replacing
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

Common questions in Woolmer Hill
Is Woolmer Hill in your area for new build mastic?
Yes, Woolmer Hill is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Woolmer Hill?
Yes. Woolmer Hill is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
How long does new build mastic take?
It depends on the size of the job, but most jobs take a few hours in a single home. We will give you a better idea when we quote.
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’ll cut it out and reseal it.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Common problems we fix in Woolmer Hill
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Look out for any of the following:
- Leaking shower tray seals in a new home
- Gaps between new skirting and floors
- Beads laid onto grit and dust from the build
- Plot mastic for developers ahead of handover
In and around Woolmer Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
