About our new build mastic in West Green
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on kitchens, windows & doors and skirting & floors, and common reasons people get in touch are gaps opening as the house dries out and settles and kitchen sealant that has pulled off the wall.
If you’ve bought a new home in or near West Green, 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.
Your job is guaranteed for a year, as with all our work.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Check bath and shower seals every few months as the house settles
- Avoid scourers and strong chemicals on sealant
- Follow the cure time we give you
- Resist patching a failed seal with a tube from the DIY shop
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
How we quote for new build mastic
Every job gets its own quote. These are the things that affect it:
- The product the joint needs
- The number and length of the joints
- How easy the joints are to reach
- The old material and how stubborn it is
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- Any previous sealing or DIY work
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
What happens if it’s left?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a smaller place like West Green, 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.
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, and we’ll explain the quote if you ask.
What you get with us
- Sealant colour chosen to suit
- Old sealant always removed completely

FAQs for West Green
Will you come out to West Green?
Yes. West Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Crawley 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’ll send you a clear quote.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Who should fix failed sealant in a new build?
Start with the builder if you are in the snagging or warranty period. Once that’s done, or if they will not put it right, we can reseal it properly.
Are you fully insured?
Yes. Full insurance covers our work.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. In a smaller place like West Green, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky

Advice
Surface by surface
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.
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.
What new build mastic looks like in West Green
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. West Green is part of Crawley, one of the post-war new towns. Newer neighbourhoods have been added to Crawley over the years, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Newer homes need snagging; older ones need their joints renewing.
For new homes near Crawley station, it’s worth checking the sealant early, while snags are still fresh. In and around West Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
