New build mastic for homes and businesses in Newton Leys
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. If you have new-build shower sealant that has already split and skirting joints opening in the first winter, we can put it right, on skirting & floors, show homes and kitchens alike.
Where new homes go up in smaller places like Newton Leys, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What the job involves on each surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.

Landlord and commercial work in Newton Leys
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too in Newton Leys and across Milton Keynes. We can quote a run of properties together.
Why it’s worth doing now in Newton Leys
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time. Homes in smaller places like Newton Leys can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- An ARBOMaster approved applicator
- Arbo and Everbuild products
- Anti-fungal silicone where joints get wet
- White, clear, grey or another colour, product permitting
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
- Cracked trays, tiles or worktops

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

- Cracked caulk along new skirting
- Messy sealant that spoils new finishes
- Kitchen sealant that has pulled off the wall
- Sealant work across a run of new homes
Around Newton Leys, as everywhere, new build mastic is only as good as the preparation behind it.

The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours for most snagging lists, longer for a run of plots. Parking around Newton Leys is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
