New build mastic in Westcott Barton
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. If you have gaps opening as the house dries out and settles and second-fix sealing on new plots, we can help, on show homes, windows & doors and skirting & floors alike.
Somewhere as small as Westcott Barton, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Ventilate bathrooms well, especially in the first year
- Wait for the cure time before using a resealed shower
- Check bath and shower seals every few months as the house settles
- Record problems with dated photos
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Questions from Westcott Barton
Will you come out to Westcott Barton?

Can you help a landlord with a rental near Heyford station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Can you quote for more than one area?
Yes. Just list everything you need and you will get one quote.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Should I go to my builder first?
Report it to the builder first while you are covered. If it isn’t resolved, we can reseal it properly.
