Advice
External mastic in Bitterne Manor, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. If you’re dealing with joints pointed up with cement by mistake and cracked joints where brick meets render or frames, we can put it right.
Houses in smaller places like Bitterne Manor can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That is where gutter joints and wall joints tend to fail first.
All of our work is guaranteed for twelve months, in Bitterne Manor and everywhere else we cover.

- Subsidence or other structural problems

What else we do in Bitterne Manor
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
- Deal with leaking gutters that soak the joints below
- Avoid pressure-washing directly into sealant joints
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
What we’re called out for in Bitterne Manor
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Signs it’s time to call us include:
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
- Cracked joints where brick meets render or frames
- Panel joints letting water in
Schools such as Bitterne Manor Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Outside joints around Bitterne Manor
Bitterne Manor is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Bitterne station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of St Denys, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Bitterne Manor: your questions answered
Is external mastic in a coastal place like Bitterne Manor any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you work for landlords with property near Bitterne station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Are you insured?
Yes. We are fully insured for every job we do.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
