Polstead questions
What guarantee comes with new build mastic in Polstead?
All our work, in Polstead and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will you come out to Polstead?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. If something is not sealant, we’ll say so.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before work begins.
How we handle new build mastic in Polstead
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you’re dealing with cracks appearing as a new home settles and leaking shower tray seals in a new home, we can put it right.
Older homes in small places like Polstead often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

When it is not the sealant
We will not take on work that won’t last, so these are the limits:
- Your warranty claim itself, which is between you and the builder
- Cracked trays, tiles or worktops
- Movement caused by a poorly fitted tray or bath
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. In a small place like Polstead, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

Do you need new build mastic in Polstead?
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
People usually contact us when they notice one of these:
- Gaps opening as the house dries out and settles
- Gaps between new skirting and floors
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
Whether the job is in Polstead itself or nearby, the right material for each joint matters as much as a neat finish.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
