Why act early in North Waltham
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. In a small place like North Waltham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why book with us
- White, clear, grey or coloured to suit, where the product allows
- Tidy, careful work
- Trusted Arbo and Everbuild sealants
- We’re fully insured

What we do, step by step
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere like North Waltham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
How to prepare

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Do you need new build mastic in North Waltham?
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
If you can see any of these, it’s time to have the joints looked at:
- Gaps behind new kitchen upstands
- Plot mastic for developers ahead of handover
- Internal frame sealant that has split
- Joints pulling apart as timber shrinks
For new homes near Micheldever station, it’s worth checking the sealant early, while snags are still fresh.

Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can new sealant go on top of the old bead?
