New-build mastic & snagging in Egham, Surrey
Problem with your new-build sealant joints in Egham? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Messy sealant that spoils new finishes
- Gaps opening as the house dries out and settles
- Sealant that never bonded to the surface
The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most snagging lists, longer for a run of plots. In Egham, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Tell us if parking is tricky
- Tell us about any water getting in
- Clear the area around the work

Advice
New build mastic in Egham, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. If you have gaps between new skirting and floors and cracks appearing as a new home settles, we can help, whatever the surface.
In a town like Egham, skirting and floor joints open up as homes settle and floors move with the seasons. Those joints need a flexible sealant, as rigid filler soon cracks out.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Work for landlords, hotels and businesses
We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
If you manage several properties in or around Egham, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
When to call us in Egham
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
It’s worth asking for a quote if you see:
- Cracks appearing as a new home settles
- Gaps behind new kitchen upstands
- Cracked sealant around new window and door frames
- Sealant that never bonded to the surface
In and around Egham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- When the joint can take water or movement
- Which sealant they’ll use, and why
- Is VAT in the price?
- Who turns up on the day
What the job involves on each surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
When something else is needed
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Broken tiles or a split tray
- Cracking that points to a structural problem
- Disputes or warranty claims with your builder
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on

What affects the cost of new build mastic
Call for a quick quote. What matters most is:
- Any working-time requirements on site
- The amount of work
- Whether there’s mould to deal with
- The number of rooms or windows
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the property is
- Photos by email, if that is easy
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or drop us an email.

When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Are you insured?
Yes. Full insurance covers our work.
Can I send you my snagging list?
Yes. Send it with pictures and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
