Coggeshall New Build Mastic
New build mastic across Coggeshall and nearby, with every bit of old sealant taken out first.
- Untidy sealant flagged on a snagging list
- Cracked caulk along new skirting
- Worktop and upstand sealant coming away
Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
New build mastic in Coggeshall, done properly
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you’re dealing with shower seals failing in the first year or two and gaps behind new kitchen upstands, we can put it right, on skirting & floors, bathrooms & en suites and show homes alike.
If you’ve bought a new home in or near Coggeshall, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Keeping the joints in good condition
Looking after new joints is easy:
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with straight away
- Follow the cure time we give you
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and protects the rest of the house.
What we do, step by step
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours in a single home in most cases. Parking around Coggeshall is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Disputes or warranty claims with your builder
- Movement caused by a poorly fitted tray or bath
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- How many areas need sealing
- Any working-time requirements on site
- Mould in or behind the old joints
- How easy the joints are to reach
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:

- If someone has resealed it before
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking

Common questions in Coggeshall
I let a flat near Kelvedon station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Will you come out to Coggeshall?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we will say so.
What do you need from me for a quote?
Let us know what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you’re unsure which you have, phone 0345 464 0079 or email us with pictures and we will tell you. Homes in smaller places like Coggeshall can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

- Gaps opening as the house dries out and settles
- Second-fix sealing on new plots
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
For new homes near Kelvedon station, it’s worth checking the sealant early, while snags are still fresh.
