Facade sealing in Stanmore
Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you have discoloured or dirty facade joints and air leaks through failed facade joints, we can put it right, whatever the surface. Whoever orders the work in Stanmore, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
On a small site around Stanmore, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.
Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email us and we’ll arrange a return visit.

What else we do in Stanmore
Your questions answered
Do you take on work at healthcare sites like Royal Hampshire County 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 Bar End Industrial Estate, close to Stanmore?
Yes. Estates, retail parks and business parks around Stanmore, Bar End Industrial Estate among them, are all within reach. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Can you look at water coming in around a frame?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we’ll be honest about which it is.
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.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, which many sites require.
What type of sealant goes on window perimeters?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, depending on the substrate and the specification.
How is access to upper-level joints handled?
That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we’ll plan the work with you.
Leave it or put it right?
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once. For buildings in places like Stanmore, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Why us?
- A fixed quote before work starts
- Colour options checked against the specified product
- Specification-led, product-correct work
- Coloured sealants to suit the setting, where available

On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. For a job in Stanmore, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- 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.
- The completed runs are checked with you, then the 12-month guarantee applies.
Before we start on site
- Let us know about inductions and permits
- Explain the parking and delivery arrangements
- Send your site hours and access windows

Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Walk the elevations once or twice a year
- Plan facade sealing alongside redecoration
- Brief window cleaners about newly sealed joints
- Keep the sealant details on the building file
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Damaged frames that need replacing
- Specialist high-level access methods
Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly.
Surfaces we seal
- Window and door perimeters
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Stone and brick facade joints
- Coping and flashing joints
- Shopfront frames
New build and refits around Stanmore
Plenty of hotels sit less than 2 miles from Stanmore. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. At about 62 miles from central London, Stanmore is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
Recladding or extending a unit at a site like Bar End Industrial Estate, 1.2 miles to the east of Stanmore, brings panel joints and frame perimeters into the programme. Further education sites such as Peter Symonds College, 1.3 miles north-east of Stanmore, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Do you need facade sealing in Stanmore?
Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.
Common reasons buildings call us in:
- Cladding panel joints that have opened up
- Previous reseals run over old sealant
- Weathered facade joints that have lost their grip
- Air leaks through failed facade joints
Hospital estates such as Royal Hampshire County Hospital (to the north of Stanmore) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
