Advice
How we handle new build mastic in Tulse Hill
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 reaches anything behind it. If you are dealing with sealant work across a run of new homes and worktop and upstand sealant coming away, we can put it right.
New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Why it’s worth doing now in Tulse Hill
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A few things move the cost up or down: 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.
Why us?
- Tidy, careful work
- 12-month guarantee on every job
- Domestic, commercial and hotel work
- 20+ years of sealant experience

Questions from Tulse Hill
Is parking a problem for a job in Tulse Hill?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
I let a flat near Tulse Hill station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
How long does new build mastic take?
That depends on how much there is to do, but most jobs take a few hours for most snagging lists, longer for a run of plots. We will tell you when we quote.
Can you do plot mastic on a new development?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we will quote.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. If that doesn’t work out, we are happy to quote with our 12-month guarantee.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Different surfaces, different methods
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing to keep callbacks down.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Do not wait for the house to settle if water is getting through
- Put sealant faults on your snagging list early
- Look at the sealant regularly in the first couple of years
- Photograph failed sealant before it’s redone
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
