Joints and finishes in East Langdon homes
East Langdon is within about 3 miles of 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Martin Mill station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic for homes and businesses in East Langdon
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on windows & doors, show homes and skirting & floors, and people most often call us about internal frame sealant that has split and sealant applied over dusty or wet surfaces.
Around East Langdon, older homes often have timber floors that move through the year, 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 to look after the new joints
So the new joints stay in good condition:
- Raise failed sealant with the developer while you are covered
- Resist patching a failed seal with a tube from the DIY shop
- Keep photos and emails about snagging items
- Wipe joints with warm soapy water
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
What we are called out for in East Langdon
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 first.
Look out for these signs:
- Cracked caulk along new skirting
- Sealant applied over dusty or wet surfaces
- Cracked sealant around new window and door frames
- Cracks appearing as a new home settles
Around East Langdon, as everywhere, new build mastic is only as good as the preparation behind it.

Do I need to be at home?

Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme ready for handover. Tell us the plots and the joints involved and we’ll quote.
Should I go to my builder first?
Start with the builder if you are in the snagging or warranty period. Once that is done, or if they will not put it right, we can reseal it properly.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

What affects the quote in East Langdon
We quote each job individually. This is what makes a difference:
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- The product the joint needs
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
To make quoting easier, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Access, such as stairs, a lift or height
- If someone has resealed it before
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, call 0345 464 0079 or send us an email.
What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
