New build mastic for homes and businesses in Otford
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We’re often asked to deal with kitchen sealant that has pulled off the wall and new-build shower sealant that has already split, across bathrooms & en suites, kitchens and skirting & floors.
For a new home in or near Otford, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
All our work is covered by a 12-month guarantee, wherever you are in Kent.

Looking after it afterwards
Looking after new joints is easy:
- Wipe joints with warm soapy water
- Keep pictures and emails about snagging items
- Put sealant faults on your snagging list early
- Don’t seal over failed sealant yourself
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.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.

FAQs for Otford
I let a flat near Otford station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is Otford within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How do I get a quote for new build mastic in Otford?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we’ll quote.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it with our one-year guarantee.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Why it’s worth doing now in Otford
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. In a smaller place like Otford, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

When to call us in Otford
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Most people get in touch after spotting something like this:
- Cracked caulk along new skirting
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
- Smeared, uneven beads picked up at snagging
For new homes near Otford station, it’s worth checking the sealant early, while snags are still fresh.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
