Questions we’re asked in Hatch End
Can you work on a hospital site such as Cygnet Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Can work at a site such as Westminster University fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Which sealant do you use on facades?
The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.
Do you replace windows or glass?
No. A glazing contractor handles that. What we seal are the joints around frames and panels.
Do you provide access for facade work?
That comes down to the access arranged for the job. When you speak to us on 01277 525 020 or email the details over, describe the access.
Can you just add new sealant on top?
No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
Facade sealing for commercial buildings in Hatch End
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. We work on shopfront frames, perimeter joints where frames meet the structure and stone and brick facade joints, and the usual reasons a site gets in touch are weathered facade joints that have lost their grip and new sealant peeling off old mastic. Whether you call it commercial sealant work, mastic application or joint sealing, in Hatch End it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Walk the elevations once or twice a year
- Combine resealing with other works that need access
- Brief window cleaners about newly sealed joints
- Check that rainwater leaves the facade the way it was designed to
Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

On site: what to expect
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. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- 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.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings
- Have the specification and drawings to hand

Advice
When to call us in Hatch End
When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.
Any of the following is a good reason to get the joints checked over:
- Staining on stone next to old sealant
- Patch repairs that keep failing
- Damp patches beside frames after rain
- Failed seals around shopfront and entrance frames
When units on a site such as Waverley Industrial Park (to the east of Hatch End) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Quoting for work in Hatch End
We price every job individually. The things that drive the figure:
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
- How much existing material needs removing
- The site’s rules and procedures
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.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- Anything awkward about access or site hours
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
- Where the site is, with the postcode
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email the details over.

What the job involves on each surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone.
