New build mastic in Hillgrove, done properly
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Common call-outs are for joints pulling apart as timber shrinks and shower seals failing in the first year or two, across windows & doors, show homes and bathrooms & en suites.
Older homes in small places like Hillgrove often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Common problems we fix in Hillgrove
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry before the sealant goes on.
Most people get in touch when they notice one of these:
- Plot mastic for developers ahead of handover
- Sealant that never bonded to the surface
- Skirting joints opening in the first winter
- Shower seals failing in the first year or two
If you’ve bought a new home near Smallbrook Junction station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before you book anyone
- How the colour is chosen
- Whether they seal over old material or remove it
- What product goes in the joint
- How the joint is cleaned and prepared
Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. Around Hillgrove, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Why book with us
- White, clear, grey or coloured to suit, where the product allows
- Domestic, commercial and hotel work
- Old sealant always removed completely
- Tidy, careful work

How the visit works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes a few hours in a single home. In a small place like Hillgrove, access is normally the main thing to plan. 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.
- 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.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we’re working on
- Mention if the joints have been sealed before

Is Hillgrove within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Yes. We are fully insured for domestic and commercial work.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Watch for new gaps as the house dries out
- Use the extractor fan every time you shower
- Record problems with dated photos
- Act quickly if a seal starts to leak
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
