Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Never let anyone seal over old sealant
- Investigate damp beside windows promptly
- Combine resealing with other works that need access
- Clear debris that holds water against joints
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards using a matching sealant.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones inside the building.
How we handle facade sealing in Pinner
Managing agents and owners in Pinner ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. Site teams most often ask us about old perimeter mastic that has dried out and leaks at window and door perimeters, on window and door perimeters, shopfront frames and cladding panel joints. One point of contact handles commercial sealant work in Pinner from the first photos to the final walk-round, whether it’s one building or several.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Do you need facade sealing in Pinner?
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Look out for the following:
- Failed sealant on precast panel joints
- Perimeter sealant that has split or peeled away
- Patch repairs that keep failing
- Draughts around frames and panels
When units on a site such as Waverley Industrial Park (to the east of Pinner) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Replacing glass or failed glazing units
- Render or concrete edges that have broken away
- Specialist high-level access methods

Leave it or put it right?
Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

FAQs: Pinner
Can you take on a job at a hospital such as Cygnet Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Waverley Industrial Park, near Pinner, within your area?
Yes, sites like Waverley Industrial Park are within our area, along with the rest of Pinner. Photos and a short description are enough for a first look.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Is colour matching possible?
It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Facade sealing in Pinner: the local picture
The ULEZ covers the whole of Greater London, Pinner 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.
Further education sites such as Christ the Redeemer College (1.4 miles south-east of Pinner) are extended and refurbished from time to time, with mastic often programmed into the summer break. Projects at schools like West Lodge Primary School work to term dates, so mastic is programmed tightly.

On site: what to expect
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For a job in Pinner, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
