Our applicators work in Lee-over-Sands on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.

- Skirting joints opening in the first winter
How we handle new build mastic in Lee-over-Sands
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. We are often asked to deal with gaps between new skirting and floors and joints pulling apart as timber shrinks, on skirting & floors, show homes and plot handovers.
Older homes in small places like Lee-over-Sands often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours in a single home, depending on the size of the job. Somewhere as small as Lee-over-Sands, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.

New build mastic around Lee-over-Sands
Lee-over-Sands is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. 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.
In and around Lee-over-Sands, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Signs you need new build mastic in Lee-over-Sands
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Any of these means the joints need attention:
- Untidy sealant flagged on a snagging list
- Sealant applied over dusty or wet surfaces
- Skirting joints opening in the first winter
- Cracked sealant around new window and door frames
If you’ve bought a new home near Clacton-On-Sea station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Lee-over-Sands: your questions answered
Do you cover Lee-over-Sands for new build mastic?
Yes. We work across London and the South East, and Lee-over-Sands is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Do you cover smaller places like Lee-over-Sands?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Why it’s worth doing now in Lee-over-Sands
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Around Lee-over-Sands, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What the job involves on each surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
