New build mastic in Upper Eashing
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you have smeared, uneven beads picked up at snagging and beads laid onto grit and dust from the build, we can help, on windows & doors, show homes and bathrooms & en suites alike.
Older homes in small places like Upper Eashing 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 there’s a problem with our work within the year, let us know and we’ll sort it.

What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes anything from a few hours to several days, depending on the number of plots. Somewhere like Upper Eashing needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.

Your questions about new build mastic in Upper Eashing
Is Upper Eashing within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Godalming station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
How we quote for new build mastic
Your quote is based on your job. We take into account:
- How many areas need sealing
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- What’s wrong with the joints now
- The type of property
- Access, such as stairs, a lift or height
- If someone has resealed it before
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

Should I try it myself first?
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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Honest limits
Sealant is not the answer to every problem, and we will tell you before any work starts. It will not solve:
- Baths and trays that move too much for sealant to cope with
- Deciding who is responsible under a builder’s warranty
- Broken tiles or a split tray
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Looking after it afterwards
So the new joints stay in good condition:
- Put sealant faults on your snagging list early
- Ventilate bathrooms well, especially in the first year
- Look at the sealant regularly in the first couple of years
- Do not wait for the house to settle if water is getting through
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
How the job changes by surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
