Common questions from Upper Norwood clients
Do you take on work at healthcare sites like British Home & Hospital for Incurables?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Will you plan work around the academic year at somewhere like King's College London?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Is Upper Norwood in your area?
Yes. We cover Upper Norwood and the rest of Greater London. For a quote, phone 01277 525 020 or send details through our quote form.
What will the job cost?
Each job is quoted on its own details. To get one, call the office on 01277 525 020 or use the quote form with a description of the work.
Can staff carry on working while you are here?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Facade sealing in Upper Norwood
External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. If you have cold air coming in at window perimeters and weathered facade joints that have lost their grip, we can put it right. Whoever orders the work in Upper Norwood, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Upper Norwood must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

What we’re called out for in Upper Norwood
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.
Clients typically get in touch after noticing something like this:
- Water coming in around window frames
- Failed seals around shopfront and entrance frames
- Facade joints cracked through the middle
- Patch repairs that keep failing
Hospital estates such as British Home & Hospital for Incurables, 0.9 miles to the west of Upper Norwood, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether their applicators hold CSCS cards
- Is the sealant right for the movement and the substrate?
How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
- Backing rod, priming and other preparation
- Location, for remote and island sites
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Send us:
- Asbestos survey details if the building is older
- Your programme or deadline
- How the joints are reached, and at what height
- The product your specification calls for
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email a schedule or drawings with what you know.

Why it’s worth doing now in Upper Norwood
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure, often turning up far from the joint. In Upper Norwood, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you’re ready.

From enquiry to sign-off
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. In Upper Norwood, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- 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.
- 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.
Preparing the site
- Let building users know which areas are affected
- Send your site hours and access windows
- Tell us what induction or permit system the site runs

Surface by surface
Precast concrete panels
Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported first.
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, and mask the edges carefully.
