New-build mastic & snagging in Twyford, Hampshire
Problem with your new-build sealant joints in Twyford? We remove the old material, prepare the joints and seal them properly.
- Smeared, uneven beads picked up at snagging
- Sealant work across a run of new homes
- Internal frame sealant that has split
Looking after it afterwards
Aftercare is simple:
- Avoid scourers and strong chemicals on sealant
- Record problems with dated photos
- Look at the sealant regularly in the first couple of years
- Get a leaking seal dealt with straight away
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Small faults turn into leaks if left.
New build mastic in Twyford
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. If you are dealing with leaking shower tray seals in a new home and kitchen sealant that has pulled off the wall, we can help, whatever the surface.
In a village or hamlet like Twyford, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Your job is guaranteed for a year, as with all our work.

Twyford questions
Do you cover Twyford for new build mastic?
Yes, Twyford is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
Can you help a landlord with a rental near Shawford station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Do you work through snagging lists?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
What information do you need?
Let us know what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
Should I wait before resealing?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the number of plots, and the area is left clean. Somewhere like Twyford needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
