About our new build mastic in Northiam
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. We are often asked to deal with cracks appearing as a new home settles and untidy sealant flagged on a snagging list, across kitchens, bathrooms & en suites and show homes.
Work in a small place like Northiam just needs the journey and access planning, and the work itself is the same as on any site.
Whatever the size of the job, you get the same 12-month guarantee in Northiam and across East Sussex.

What the job involves on each surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
Plot handovers
Developers can send the plot schedule and specification for a quote. We seal bathrooms, kitchens, frames and floors as agreed.
Landlord and commercial work in Northiam
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
We also work for property managers and facilities teams in Northiam and across East Sussex. Several sites can go on one quote.
What we are called out for in Northiam
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Any of these means the joints need attention:
- Plot mastic for developers ahead of handover
- Kitchen sealant that has pulled off the wall
- Untidy sealant flagged on a snagging list
- Cracked sealant around new window and door frames
Whether the job is in Northiam itself or nearby, the right material for each joint matters as much as a neat finish.
What your quote should include
- What happens if they find a problem under the old sealant
- Who does the work, and how experienced they are
- Is VAT in the price?
- What the cure time is

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours in a single home, depending on the amount of work. Somewhere like Northiam needs a little journey planning: 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

When it isn’t the sealant
To be straight with you, there are a few things sealant will not fix:
- Leaks from pipes, valves or wastes, which need a plumber
- Structural cracks in walls or ceilings
- Disputes or warranty claims with your builder
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before booking.

FAQs for Northiam
Is Northiam within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Northiam in your area for new build mastic?
Yes, Northiam is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
What does new build mastic cost?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.
Should I wait before resealing?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Why deal with it now?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Northiam can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
