About facade sealing in Portsmouth
A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. Site teams most often ask us about perimeter sealant that has split or peeled away and failed sealant on precast panel joints, on stone and brick facade joints, perimeter joints where frames meet the structure and shopfront frames.
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.

New build and refurbishment in Portsmouth
Across Portsmouth, refurbishment brings as many facade and perimeter joints as new build: replacement windows, recladding and fit-outs in places such as Southsea, Milton and Landport. Each junction between new and existing materials needs the right sealant, primer and backing.
The South East has large numbers of business parks and industrial estates, especially around the motorway corridors, and we cover Portsmouth along with the rest of the region. Along the coast in Portsmouth, hospitality buildings tend to be busiest in the summer months, so work is often best planned for quieter months.
Portsmouth: For a contractor at a hotel such as The Avenue Hotel, 1 mile to the north of Portsmouth, the mastic often has to be finished before a reopening date. Units on estates such as Victory Retail Park (to the west of Portsmouth) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
After the work
To get the most from the new sealant:
- Insist on a full cut-out when joints are renewed
- Keep the sealant details on the building file
- Plan facade sealing alongside redecoration
- Check that rainwater leaves the facade the way it was designed to
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade instead of soaking the joints.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.
Why it fails
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Common reasons buildings call us in:
- Unsightly perimeter sealant on a visible elevation
- Perimeter joints where frames meet the structure
- Cold air coming in at window perimeters
- Perimeter sealant that has split or peeled away
When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Providing access systems for the work
- Movement beyond what any sealant can handle
- Damaged frames that need replacing
Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Why deal with it now?
The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple.

Questions we are asked in Portsmouth
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
Is Portsmouth in your area?
Yes. We cover Portsmouth, and you can phone 01277 525 020 or send photos by email to get started.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
How do we ask for a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
Can you look at water coming in around a frame?
Yes. Photos help, and you can give us a call on 01277 525 020 or email us to arrange a visit. Many frame leaks are sealant failures, though not all, and we will tell you which.
