About our new build mastic in Middle Wallop
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you are dealing with cracked caulk along new skirting and worktop and upstand sealant coming away, we can put it right, whatever the surface.
Older homes in small places like Middle Wallop often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Why deal with it now?
A hairline gap at a skirting can wait, but a leaking seal can’t. If you’re unsure which you have, ring 0345 464 0079 or email us with photos and we will tell you. In a small place like Middle Wallop, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we will talk you through it.

The most common problems we see are:
- Gaps opening as the house dries out and settles

Middle Wallop: your questions answered
Do you cover smaller places like Middle Wallop?

We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
Can you do plot mastic on a new development?

What does new build mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
What affects the quote in Middle Wallop
Some jobs are bigger than they look, and some smaller. The main factors:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Any mould that needs treating
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Middle Wallop, the journey is planned in advance: 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 start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
How to prepare
- Let us know if you’ve seen damp or leaks
