Facade sealing for commercial buildings in Monkhams
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’re dealing with cladding panel joints that have opened up and unsightly perimeter sealant on a visible elevation, we can help. For commercial sealant work in Monkhams, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around Monkhams, 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.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Work for main contractors and building owners
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Monkhams can sit alongside others in a wider programme across Greater London.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Why deal with it now?
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
On site: what to expect
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- 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.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Send your site hours and access windows
- Let us know about inductions and permits
- Confirm the product named in the specification
Quotes
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Common questions from Monkhams clients
Will you plan work around the academic year at somewhere like University of Portsmouth Walthamstow Campus?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is hospital work, at somewhere like The Holly Private Hospital, something you do?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What will the job cost?
Each job is quoted on its own details. To get one, phone 01277 525 020 or use the quote form.
Is Monkhams in your area?
Yes. We cover Monkhams, and you can give us a call on 01277 525 020 or email us to get started.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What we are called out for in Monkhams
When the sealant tears down its centre, it has usually been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
Most enquiries start with one or more of the following:
- Facade joints cracked through the middle
- Old perimeter mastic that has dried out
- Previous reseals run over old sealant
- Gaps between rainscreen or cladding panels
For contractors refurbishing units at places like Woodford Trading Estate (1.9 miles south of Monkhams), the mastic covers cladding panels, roller-door and window perimeters.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- Their plan for phasing and protecting the area
- Is the sealant right for the movement and the substrate?
- Their approach to joint depth and backing
Aftercare for building managers
A few simple habits keep the new joints working:
- Avoid patch repairs on failed facade joints
- Investigate damp beside windows promptly
- Share access with other external trades
- Ask about asbestos in pre-2000 mastic
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in instead of after the damage.
