New build mastic in Hayes: local notes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Hayes & Harlington station, the sealant around baths, showers and frames is worth checking in the first year or two. As a London address, Hayes can be tricky for parking: let us know about parking bays, permits or a driveway.
Hayes is about 8 miles east of Slough, in Greater London. Jobs in Hayes get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee.

New build mastic in Hayes
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. We work on windows & doors, show homes and bathrooms & en suites, and the jobs we see most are gaps between new skirting and floors and cracked sealant around new window and door frames.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Every job comes with our one-year guarantee.

What else we do in Hayes
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the 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.
Common questions in Hayes
Do you cover Hayes for new build mastic?
Yes. Our work covers London and the South East, and Hayes is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Can parking be tricky for a visit in Hayes?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
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.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.
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.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a few hours for most snagging lists, longer for a run of plots. In Hayes, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property

Surface by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in.
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Quotes for new build mastic in Hayes
Every job gets its own quote. This is what makes a difference:
- Access and height
- The old material and how stubborn it is
- Any mould that needs treating
- The type of sealant required
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Any access issues, like height or stairs
- What’s wrong with the joints now
- Where the property is
- How many joints, rooms or windows are involved
To get a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Raise failed sealant with the developer while you’re covered
- Keep water off fresh sealant until it has cured
- Get a leaking seal dealt with right away
- Resist patching a failed seal with a tube from the DIY shop
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
