Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
New build mastic for homes and businesses in Halstead
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you have gaps opening as the house dries out and settles and frame joints opening as the plaster dries, we can put it right, on bathrooms & en suites, kitchens and plot handovers alike.
Small business units and shops in a town like Halstead have floors that take heavy wear. Joints at thresholds and in tiled or concrete floors need resealing before the edges start to break up.
Each job carries a 12-month guarantee, whatever its size.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Report sealant problems to your builder during the snagging period
- Record problems with dated pictures
- Act quickly if a seal starts to leak
- Wipe joints with warm soapy water
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
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.

Why act early in Halstead
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. Black mould and gaps in sealant do not fix themselves, and in a busy home in Halstead they get worse with every use. Replacing the sealant now is the simplest fix.
Doing several joints on one visit is generally more efficient than separate visits. We will send you a clear quote for the lot.

What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Cracking that points to a structural problem
- Baths and trays that move too much for sealant to cope with
- Disputes or warranty claims with your builder
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

What the job involves on each surface
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.
New homes and floors in Halstead
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Should I try it myself first?
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, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
