Facade sealing in Rudmore
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What happens if it’s left?
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure. For buildings in places like Rudmore, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Facade sealing in Rudmore
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. If you have gaps between rainscreen or cladding panels and air leaks through failed facade joints, we can help. Most enquiries from Rudmore start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Conversions around smaller places like Rudmore often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Work in places the size of Rudmore is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
What we need from you
- Send any specification or drawings in advance
- Send asbestos survey details if the building is pre-2000
- Warn occupants and staff about the work

Facade sealing in Rudmore: the local picture
The sea is no more than about 1 mile from Rudmore. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. Plenty of hotels sit less than 2 miles from Rudmore. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
For contractors refurbishing units at places like Victory Retail Park, which lies south-west of Rudmore, the mastic covers cladding panels, roller-door and window perimeters. For a contractor working at a hospital such as St James Hospital, which lies south-east of Rudmore, perimeter and facade sealing is planned around patients and deliveries. On a campus such as University of Portsmouth - North Zone (1.3 miles south-west of Rudmore), new teaching buildings and residences are normally built and refurbished around the academic year.
Rudmore is about 1 mile north-west of Portsmouth, in Portsmouth. Our applicators travel to Rudmore for work on facade joints. Rudmore is one of 19 places in Portsmouth on our list.

Cost factors for facade joints
Your fixed quote is built from the real scope. It allows for:
- Whether old sealant has to be cut out first
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
- Travel to remote or island sites
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- The type of building and who uses it
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or speak to us on 01277 525 020 or email us if you’d rather talk the job through.
What the job involves on each surface
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in.
Brick and stone facades
Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.
Building owners, agents and FMs in Rudmore
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Rudmore. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Your questions answered
Does the sea air around Rudmore change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
Can you work around term dates at a campus such as University of Portsmouth - North Zone?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you find out why a window is leaking?
Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
