Common problems we fix in Edgware
Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.
Any of the following is a good reason to get the joints checked over:
- Water coming in around window frames
- Hard, chalky sealant that no longer flexes
- Patch repairs that keep failing
- Perimeter sealant that has split or peeled away
For contractors at a college like Stanmore College, which lies west of Edgware, perimeters and internal sealant are timed for the holidays.

Facade sealing in Edgware, done properly
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on cladding panel joints, window and door perimeters and perimeter joints where frames meet the structure, and the failures we are asked to look at most are cold air coming in at window perimeters and staining on stone next to old sealant. Facilities teams, main contractors and managing agents in Edgware tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Edgware must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Doing it in-house
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. 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.
Facade sealing in Edgware: the local picture
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Edgware. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. A 2-mile radius around Edgware takes in a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Recladding or extending a unit at a site like Mill Yard Industrial Estate (1 mile south of Edgware) brings panel joints and frame perimeters into the programme. New wings at hospitals like Edgware Community Hospital (0.9 miles south of Edgware) bring long runs of window and panel joints to seal.

Work for main contractors and building owners
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Edgware: questions and answers
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Will you plan work around the academic year at somewhere like Middlesex University?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you guarantee your work?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.
Should we check old sealant for asbestos?
It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. Suspect material is left alone until it has been tested.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What else we do in Edgware
Cost factors for facade joints
The price varies from site to site. It mainly depends on:
- Removal of failed or old sealant
- The total length or number of joints
- Induction, permit and paperwork requirements
- Any access equipment needed
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- Approximate linear metres or a joint schedule
- Any specification or named product
- Any dates the work must fit around
- Photos of the joints, close up and from further back
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We plan access and the order of elevations with the client.
- 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.
Getting the site ready
- Warn occupants and staff about the work
- Flag any permit to work we will need
- Arrange parking or a loading space

Honest limits
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Cracked or spalling substrates that need repair before sealing
- Installing or repairing glazing systems
- Leaks from roofs, gutters or failed flashings rather than sealant joints
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
What we seal
- Cladding panel joints
- Coping and flashing joints
