Facade sealing in Norwood Green
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. Site teams most often ask us about leaks at window and door perimeters and unsightly perimeter sealant on a visible elevation, across shopfront frames, perimeter joints where frames meet the structure and stone and brick facade joints. For commercial sealant work in Norwood Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Every London site, Norwood Green included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites typically need booked deliveries and a plan for where materials go.
Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

When to call us in Norwood Green
Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
What tends to prompt an enquiry:
- Damp patches beside frames after rain
- Failed seals around shopfront and entrance frames
- Unsightly perimeter sealant on a visible elevation
- Failed sealant on precast panel joints
Extensions at sites like Ealing Hospital, 1.2 miles to the north-east of Norwood Green, typically sit beside working departments, and the mastic follows strict access rules.
Before you book anyone
- Health and safety accreditation such as CHAS
- Will RAMS and insurance details be available?
- How they’ll work around occupants
- How long is the guarantee, and what does it include?
After the work
Problems stay small when the joints are checked regularly. Specifically:
- Avoid patch repairs on failed facade joints
- Report water ingress at frames as soon as it shows
- Confirm the survey covers external sealants in older buildings
- Brief window cleaners about newly sealed joints
Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade.
Coordinate facade sealing with other external works. One set-up for several trades saves money.

Our process
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. All of Greater London is in the ULEZ, and kerbside space in Norwood Green can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- 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.
- 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.
Before we start on site
- Move anything stored against the joints
- Tell us which areas need to stay in use
- Send your site hours and access windows

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Common questions from Norwood Green clients
Can you take on a job at a hospital such as Ealing Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work at a site such as Bridge Road Industrial Estate, by Norwood Green?
Yes. We cover Norwood Green and the area around it, including industrial estates, business parks and retail parks such as Bridge Road Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
When can you be on site?
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.
Do we need an asbestos check before resealing?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register. Suspect material is left alone until it has been tested.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Can you work on upper floors?
We agree access with the client at the start. Let us know what access is in place or planned.
Cost factors for facade joints
Your fixed quote is built from the real scope. It allows for:
- Phasing around occupants
- Which sealant the job calls for
- How much there is to seal
- Joint width, depth and condition
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Whether an asbestos survey exists
- The product your specification calls for
- Clear photographs of the problem areas
- Rough lengths or quantities, or drawings if you have them
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Doing it in-house
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
