New build mastic in Peacehaven
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We are often asked to deal with frame joints opening as the plaster dries and beads laid onto grit and dust from the build, on bathrooms & en suites, windows & doors and kitchens.
For a new home in or near Peacehaven, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

Questions from Peacehaven
Can you do new build mastic in Peacehaven?
Yes, Peacehaven is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Peacehaven?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Why does sealant fail so quickly in new builds?
There are usually two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
How long will you be here?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. Your quote will say how long we expect yours to take.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you work through snagging lists?
Yes. Send it with pictures and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Common problems we fix in Peacehaven
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
The most common problems we see are:
- Joints pulling apart as timber shrinks
- Sealant that never bonded to the surface
- Gaps behind new kitchen upstands
- Shower seals failing in the first year or two
If you’ve bought a new home near Newhaven Town station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why act early in Peacehaven
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In a smaller place like Peacehaven, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. For a job in Peacehaven, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

Advice
Different surfaces, different methods
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
What affects the quote in Peacehaven
The price is agreed before any work begins. It takes into account:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- The number and length of the joints
- Whether there’s mould to deal with
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
What to tell us for a quote
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- The type of property
- Roughly how big the job is
- Pictures of the joints, sent by email
Getting a quote is simple: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we’ll take it from there.
How to look after the new joints
So the new joints stay in good condition:
- Check bath and shower seals every few months as the house settles
- Avoid running a DIY bead over the old one
- Avoid scourers and strong chemicals on sealant
- Put sealant faults on your snagging list early
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.
