About our new build mastic in Berwick
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you have plot mastic for developers ahead of handover and cracked sealant around new window and door frames, we can put it right.
Work in a small place like Berwick just needs the journey and access planning, and the work itself is the same as on any site.
Whatever the size of the job, it’s backed by our one-year guarantee.

Quotes for new build mastic in Berwick
There’s no set price list. The quote depends on:
- The type of sealant required

- What the problem is, such as mould, gaps, leaks or cracking

What we do, step by step
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours in a single home for a typical job. Somewhere as small as Berwick, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive

Advice
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What the job involves on each surface
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Plot handovers
Send us the schedule and any sealant specification. Sealant work across the plot is covered.
Honest limits
In fairness, there are a few things sealant won’t fix:
- Movement caused by a poorly fitted tray or bath
- Leaking fittings rather than failed sealant
- Broken tiles or a split tray
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Joints and surfaces we work on
- Skirting & floors
- Plot handovers
- Bathrooms & en suites
- Kitchens

- Windows & doors
Why it’s worth doing now in Berwick
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 Berwick, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or email us.

Berwick: your questions answered
Will you come out to Berwick?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Berwick in your area for new build mastic?
Yes, Berwick is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Can you work from my snagging list?
Yes. Send it with photos and we will quote for the sealant items. If something is not sealant, we’ll say so.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
How long does new build mastic take?
Typically it takes a few hours in a single home. Larger jobs naturally take longer, and we will tell you how long to expect.
