About our facade sealing in Canons Park
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, but not always. If the evidence points away from the sealant, we say so before quoting. If you have perimeter joints where frames meet the structure and staining on stone next to old sealant, we can put it right. Looking for mastic applicators who cover Canons Park? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around Canons Park, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why it’s worth doing now in Canons Park

Failed sealant in a building in Canons Park can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.

Common questions from Canons Park clients
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. We allow for the ULEZ, which covers every borough
Can you work at a site such as Mill Yard Industrial Estate, by Canons Park?
Yes. Estates, retail parks and business parks around Canons Park, Mill Yard Industrial Estate among them, are all within reach. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Do you run new sealant over the existing bead?
No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
How many days will you need on site?
It depends on the scope, but the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
What the job involves on each surface
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end to the correct depth.

Signs you need facade sealing in Canons Park
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building, then it splits or peels.
Look out for the following:
- Patch repairs that keep failing
- Leaks at window and door perimeters
- Gaps between rainscreen or cladding panels
- Discoloured or dirty facade joints
Further education sites such as Stanmore College (to the west of Canons Park) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Facade sealing around Canons Park: what changes locally
As part of Greater London, Canons Park is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are several hotels within about 2 miles of Canons Park. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
University estates such as Middlesex University (2.2 miles south-east of Canons Park) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. New units and refits on sites such as Mill Yard Industrial Estate, 0.7 miles south-east of Canons Park, need their panel and perimeter joints sealed to the specification.

From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. 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.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
Preparing the site
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space
- Tell staff and tenants when we will be in
