Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
New build mastic for homes and businesses in Luddesdown
A new build should have a neat, sound bead at every joint. 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 are dealing with leaking shower tray seals in a new home and internal frame sealant that has split, we can put it right, on kitchens, windows & doors and plot handovers alike.
Older homes in small places like Luddesdown often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Common questions in Luddesdown
I let a flat near Sole Street station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Can you do new build mastic in Luddesdown?
Yes. We work across London and the South East, and Luddesdown is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Do you work for developers?
Yes. We work through plots to your schedule ready for handover. Tell us the plots and the joints involved and we’ll quote.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, large or small.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
How long will you be here?
As a guide, most jobs take a few hours in a single home. Bigger jobs take longer.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Get a leaking seal dealt with right away
- Record problems with dated photos
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.

What else we do in Luddesdown
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
What we’re called out for in Luddesdown
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
The most common problems we see are:
- Shower seals failing in the first year or two
- Second-fix sealing on new plots
- Frame joints opening as the plaster dries
- Gaps opening as the house dries out and settles
In and around Luddesdown, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Luddesdown, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
