What new build mastic looks like in Great Burstead

Common problems we fix in Great Burstead
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
People normally contact us after spotting one of these:
- Joints pulling apart as timber shrinks
- Skirting joints opening in the first winter
- Second-fix sealing on new plots
- Gaps behind new kitchen upstands
In and around Great Burstead, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- What product goes in the joint
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
- When the joint can take water or movement
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
- Avoid scourers and strong chemicals on sealant
- Keep photos and emails about snagging items
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
Quotes for new build mastic in Great Burstead
Your quote is based on your job. We look at:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The size of the job
- Which sealant suits the joint
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
Before you ask for a quote, have a think about:
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- The address or postcode of the job
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.
Landlord and commercial work in Great Burstead

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Why it’s worth doing now in Great Burstead
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Older cottages and farmhouses around Great Burstead can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
