About our new build mastic in Hounsdown
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. If you have skirting joints opening in the first winter and untidy sealant flagged on a snagging list, we can help, whatever the surface.
Homes around Hounsdown range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
All our work is covered by a 12-month guarantee, wherever you are in Southampton.

What new build mastic looks like in Hounsdown
Hounsdown is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Totton station, it’s worth checking the sealant early, while snags are still fresh. Around Hounsdown, as everywhere, new build mastic is only as good as the preparation behind it.
Hounsdown is about 1 mile south of Totton, in Southampton. For new build mastic in and around Hounsdown, please call 0345 464 0079 or drop us an email for a quick quote. We’re based in Crawley and cover Southampton, Hounsdown included. 40 places in Southampton are on our list, large and small.

How it works
The work is kept neat and contained to the area we are working on. Expect the work to take a few hours in a single home, and we tell you how long to leave it before we go. A visit to Hounsdown is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.

Advice
How the job changes by surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Common questions in Hounsdown
Do you work for landlords with property near Totton station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Can you do new build mastic in Hounsdown?
Yes. Our work covers London and the South East, and Hounsdown is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with pictures if you can and we will give you a quote. We will flag anything that needs another trade.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Around Hounsdown, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
- Don’t seal over failed sealant yourself
- Watch for new gaps as the house dries out
Don’t stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
