New build mastic in Marlow Bottom
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. Typical jobs include sealant applied over dusty or wet surfaces and leaking shower tray seals in a new home, across kitchens, skirting & floors and plot handovers.
Older homes in small places like Marlow Bottom often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

New homes and floors in Marlow Bottom
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Marlow station, it’s worth checking the sealant early, while snags are still fresh.

Common problems we fix in Marlow Bottom
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
These are the problems we are asked about most:
- Joints pulling apart as timber shrinks
- Shower seals failing in the first year or two
- Untidy sealant flagged on a snagging list
- Internal frame sealant that has split
In and around Marlow Bottom, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- What happens if the job turns out different
- How the surfaces are prepared before sealing
- The length of the guarantee
- Whether they’re fully insured
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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. Everything old must be removed first.
Aftercare tips
To keep the joints looking good and working properly:
- Clean sealant with mild detergent, not abrasives
- Keep pictures and emails about snagging items
- Use the extractor fan every time you shower
- Get a leaking seal dealt with straight away
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours in a single home. For a village or hamlet like Marlow Bottom, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.

What else we do in Marlow Bottom
How the job changes by surface
Windows and doors

FAQs for Marlow Bottom
Will you come out to Marlow Bottom?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Marlow station?
Yes. We work for letting agents and landlords as well as householders. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
How do I get a quote for new build mastic in Marlow Bottom?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Should I wait before resealing?
Any seal that is leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Which products do you use?
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 will tell you what we are using.
