Facade sealing for Southsea sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What affects the price in Southsea
To price the job, we consider:
- Site requirements such as inductions and permits
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
- How much there is to seal
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- Photos of the joints, close up and from further back
- Whether the building will be occupied during the work
- Any specification or named product
- The site address and postcode
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Facade sealing in Southsea
Facade sealants sit in the sun, rain and frost every day. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. Most enquiries involve perimeter joints where frames meet the structure and weathered facade joints that have lost their grip, on window and door perimeters, shopfront frames and stone and brick facade joints. Facilities teams, main contractors and managing agents in Southsea tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Construction in a town such as Southsea is often smaller schemes: a few new flats, a school extension, a refurbished unit. The perimeter and facade joints on a small scheme need the same sizing and preparation as on a big one.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we can’t put right
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Work on the window or framing system itself
- Damaged frames that need replacing
- Providing access systems for the work
If you’re not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer.
What we seal
- Window and door perimeters
- Coping and flashing joints
- Cladding panel joints
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
- Shopfront frames
Building and refurbishing in Southsea
Southsea sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Southsea has plenty of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Units on estates such as The Bridge Shopping Centre, 1 mile north of Southsea, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For contractors on a campus like University of Portsmouth, 0.6 miles to the north of Southsea, facade and perimeter sealing has to fit around students and term dates.
Southsea is about 2 miles south of Portsmouth, in Portsmouth. We send applicators to Southsea for facade joints, handled exactly as we handle every other area. Southsea is one of 19 places we cover in Portsmouth.
Postcode districts covered here: PO5, PO4 and PO1. Among the streets we cover are Bath Road, Liss Road and Beach Road, and sites on any of them can send details for a fixed quote. Close to Southsea, our area also takes in Milton (1 mile north-east), Fratton (1 mile north), Kingston (1 mile north), Landport (1 mile north-west) and Baffins (2 miles north). Nearby towns on our patch include Hilsea (3 miles north), Wymering (4 miles north), Paulsgrove (5 miles north), Cosham (4 miles north), Drayton (4 miles north) and Farlington (5 miles north).
Around Southsea
Around Southsea, our work takes us to commercial buildings near The Festing pub, St Edmund's Catholic School and Mayville High School. The nearest railway station is Fratton station, roughly 0.8 miles north of the centre. Well-known places in the area include St. Mary's Hospital (1 mile north) and Southsea Castle (1 mile south-west). The countryside around Southsea includes Milton Locks.
Why it’s worth doing now in Southsea
Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Many buildings in towns like Southsea have been extended or altered, and joints where old meets new tend to fail first. Resealing them early protects the building behind.
A quote for facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Signs you need facade sealing in Southsea
Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.
Clients typically get in touch after noticing one or more of the following:
- Staining on stone next to old sealant
- New sealant peeling off old mastic
- Draughts around frames and panels
- Perimeter joints where frames meet the structure
When a college such as Portsmouth College (1.9 miles north-east of Southsea) builds or refurbishes, the mastic package usually has to fit around students and staff.

Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If you have more than one building in Southsea, they can often be done on the same visit, with one quote covering them. Give us your access times and we will fit the work in.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
What we need from you
- Point out parking and an unloading spot
- Make sure the joints can be reached
- Tell us which areas need to stay in use

Advice
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
FAQs: Southsea
Can you work at a site such as The Bridge Shopping Centre, by Southsea?
Yes. Our area takes in Southsea and its surroundings, with estates and business parks such as The Bridge Shopping Centre included. Send details of the unit and the work through our quote form for a quick quote.
Can you work around term dates at a campus such as University of Portsmouth?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
