About our new build mastic in Sandhills
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. If you’re dealing with second-fix sealing on new plots and cracked caulk along new skirting, we can put it right, whatever the surface.
Work in a small place like Sandhills just needs the journey and access planning, and the work itself is the same as on any site.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. Somewhere as small as Sandhills, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Each area is checked and left with its cure time.
How to prepare
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height

Advice
Why act early in Sandhills
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a small place like Sandhills, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
Why choose Mr Mastic in Sandhills
- White, clear, grey or coloured to suit, where the product allows
- A sealant colour to suit the surroundings
- Experience in homes, commercial sites and hotels
- Old sealant always removed completely

What sealant work cannot fix
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Disputes or warranty claims with your builder
- A tray or bath that isn’t properly supported, until it’s fixed
- Cracked trays, tiles or worktops
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Bathrooms & en suites
- Show homes
- Windows & doors
- Kitchens
- Plot handovers
- Skirting & floors
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Sandhills questions
Can you do new build mastic in Sandhills?
Yes. We work across London and the South East, and Sandhills is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Is Sandhills within the area you cover?
Yes. Sandhills is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
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.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
