About our new build mastic in Elvendon
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. Common call-outs are for second-fix sealing on new plots and gaps behind new kitchen upstands, across skirting & floors, show homes and kitchens.
Older homes in small places like Elvendon often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Your questions about new build mastic in Elvendon
Can you help a landlord with a rental near Goring & Streatley station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Will you come out to Elvendon?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Is it worth resealing while the house is still settling?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
What should I tell you?
Tell us what needs doing and where, plus pictures if you have them. We’ll ask anything else we need to know.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Cracked trays, tiles or worktops
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.

How we quote for new build mastic
The quote reflects the job in front of us. We take into account:
- The number of rooms or windows
- Any mould that needs treating
- Access and height
- How much there is to do
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
What to tell us when you ask for a quote:
- Roughly how big the job is
- Where the property is
- Any access issues, like height or stairs
- Photos by email, if that is easy
Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or send us an email and describe the job, and photos are welcome.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Report sealant problems to your builder during the snagging period
- Avoid running a DIY bead over the old one
- Get a leaking seal dealt with right away
- Clean sealant with mild detergent, not abrasives
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
Common problems we fix in Elvendon
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
Signs it’s time to call us include:
- Cracked caulk along new skirting
- Frame joints opening as the plaster dries
- Sealant applied over dusty or wet surfaces
- Plot mastic for developers ahead of handover
Around Elvendon, as everywhere, new build mastic is only as good as the preparation behind it.
