- Installing or repairing glazing systems
If in doubt, give us a call on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

- Perimeter joints where frames meet the structure
Facade sealing for commercial buildings in Shirley
Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. If you have old perimeter mastic that has dried out and unsightly perimeter sealant on a visible elevation, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Shirley it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Building and refurbishing in Shirley
A 2-mile radius around Shirley takes in a number of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. The ULEZ covers the whole of Greater London, Shirley included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
Projects at schools like Oasis Academy Shirley Park work to term dates, so mastic is programmed tightly. Extensions at sites like Shirley Oaks Hospital, under half a mile north-west of Shirley, usually sit beside working departments, and the mastic follows strict access rules.

How the job changes by surface
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one.
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and we’ll mention any edges that need repair.

Your questions answered
Do you take on work at healthcare sites like Shirley Oaks Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Will you take on work at estates like Chaffinch Business Park, close to Shirley?
Yes. We cover Shirley and the area around it, including industrial estates, business parks and retail parks such as Chaffinch Business Park. A few photographs and the unit address let us price the work.
Can the building stay open while you work?
Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Should we check old sealant for asbestos?
In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Why deal with it now?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- 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.
Before we start on site
- Send your site hours and access windows
- Tell staff and tenants when we will be in
- Make sure the joints can be reached

Advice
For managing agents and facilities managers
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Shirley can sit alongside others in a wider programme.
Do you need facade sealing in Shirley?
Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.
It’s worth sending us details if you spot any of the following:
- Weathered joints at frame-to-structure perimeters
- Weathered facade joints that have lost their grip
- Leaks at window and door perimeters
- Failed sealant on precast panel joints
With historic properties like Addington Palace, 1.7 miles to the south of Shirley, in the area, refurbishment work often meets old masonry that needs compatible sealants.
