Questions about Freemantle
Does a coastal location like Freemantle affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Do you cover business parks and estates near Freemantle, such as Liners Industrial Estate?
Yes, sites like Liners Industrial Estate are within our area, along with the rest of Freemantle. A few photos and the unit address let us price the work.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How do we ask for a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.
How do you work with the site programme?
Our work is sequenced around the programme. Areas are sealed as they’re released by the site team, and we’ll raise anything that holds the work up.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal areas can typically carry on while the outside waits. If you have bath and shower joints scraped during the final clean and missed perimeter joints on a new elevation, we can help, whatever the surface. One point of contact handles commercial sealant work in Freemantle from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Around places like Freemantle, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Advice
Sites and facades in and around Freemantle
Freemantle is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Rainfall across the South East, Freemantle included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
Extensions at sites like Royal South Hants Hospital (1.3 miles east of Freemantle) typically sit beside working departments, and the mastic follows strict access rules. Hotels like The Bedford Hotel, 0.9 miles to the east of Freemantle, rarely close for long, so refurbishment mastic is phased floor by floor. For contractors on a campus like Southampton Solent University, 1.1 miles to the east of Freemantle, facade and perimeter sealing has to fit around students and term dates.
Freemantle is about 1 mile west of Southampton, in Southampton. Anywhere in SO15, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Southampton coverage takes in 30 places.

Why it’s worth doing now in Freemantle
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
