New build mastic in Lower Green, done properly
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. If you’re dealing with sealant that never bonded to the surface and worktop and upstand sealant coming away, we can help, on windows & doors, show homes and plot handovers alike.
Work in a small place like Lower Green just needs the journey and access planning, and once on site, the job is the same as anywhere.
A 12-month guarantee comes as standard.

Do you need new build mastic in Lower Green?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
- Gaps opening as the house dries out and settles
- Second-fix sealing on new plots
Around Lower Green, as everywhere, new build mastic is only as good as the preparation behind it.

Why act early in Lower Green
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like Lower Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear price before we start.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check bath and shower seals every few months as the house settles
- Follow the cure time we give you
- Use the extractor fan every time you shower
- Avoid scourers and strong chemicals on sealant
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day to cure enough for use.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you, so raise it early.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. For a village or hamlet like Lower Green, the journey is planned in advance: 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.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints

Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We will go through the sealant items and agree what we’ll do.
Can new sealant go on top of the old bead?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
Different surfaces, different methods
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
