Facade sealing in Wood Green
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. The enquiries we see most involve patch repairs that keep failing and cladding panel joints that have opened up, on perimeter joints where frames meet the structure, stone and brick facade joints and window and door perimeters. A single leaking joint is often how a building in Wood Green first comes to us: we look at the rest while we’re there and tell you what we find.
Around Wood Green, 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.
A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or send photos by email and we will come back to it.

For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Diagnose, treat, sign off
Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Planning a London job such as one in Wood Green starts with access. Give us the hours we can be on site and we will schedule to suit.
- 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.
Before we start on site
- Share your working hours and any access restrictions
- Tell staff and tenants when we’ll be in
- Tell us what induction or permit system the site runs

What we are called out for in Wood Green
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.
If one of these sounds familiar, it’s time for a closer look:
- Perimeter joints where frames meet the structure
- Staining on stone next to old sealant
- Damp patches beside frames after rain
- Facade joints cracked through the middle
New wings at hospitals like St Ann's Hospital, 1.5 miles to the south-east of Wood Green, bring long runs of window and panel joints to seal.

How the quote is worked out
Your fixed quote is built from the real scope. It takes account of:
- How much existing material needs removing
- Location, for remote and island sites
- Which sealant the job calls for
- Any access equipment needed
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
Sending details for a quote
Good information means a firmer quote. Helpful details to send:
- Whether the building will be occupied during the work
- Any dates the work must fit around
- Asbestos survey details if the building is older
- Where the site is, with the postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Investigate damp beside windows promptly
- Brief window cleaners about newly sealed joints
- Record the product and colour used on each elevation
- Combine resealing with other works that need access
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
Wood Green: questions and answers
Is hospital work, at somewhere like St Ann's Hospital, something you do?

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.

Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
How long will the new sealant last?

Why act early in Wood Green
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. Getting scaffold, permits or access booked in Wood Green takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Pricing facade joints depends on quantities, condition and access, and any specification that applies. Call for a quote.
