How we handle new build mastic in Hayes
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 it isn’t put right, get in touch with us. Common call-outs are for beads laid onto grit and dust from the build and cracked sealant around new window and door frames, across skirting & floors, bathrooms & en suites and kitchens.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
Big or small, it’s backed by our 12-month guarantee in Hayes and across Greater London.

FAQs for Hayes
Is parking an issue for new build mastic in Hayes?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Can you help a landlord with a rental near Hayes (Kent) station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you’re covered. Once that’s done, or if they won’t put it right, we can reseal it properly.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Should I wait before resealing?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Do you cover Hayes?
Yes. We cover Hayes. For a quote, call 0345 464 0079 or drop us an email.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Surface by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out and baths are filled before sealing.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing.
Leave it or put it right?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Common problems we fix in Hayes
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly.
If you can see any of these, it’s time to have the joints looked at:
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
- Gaps between new skirting and floors
- Gaps opening as the house dries out and settles
Hayes is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What your quote should include
- Who does the work, and how experienced they are
- How the joint is cleaned and prepared
- Whether VAT is included
- How long the guarantee is
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We cut it out and start again.

Advice
For landlords and businesses
For anyone letting property in or around Hayes, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Aftercare tips
After the cure time, these simple habits help:
- Raise failed sealant with the developer while you’re covered
- Keep photos and emails about snagging items
- Clean sealant with mild detergent, not abrasives
- Don’t wait for the house to settle if water is getting through
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
Early snagging is easier snagging. Small faults turn into leaks if left.
