Facades, frames and programmes in Streatham Hill
A 2-mile radius around Streatham Hill takes in plenty of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. Site traffic in Streatham Hill falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
Recladding or extending a unit at a site like Zennor Road Industrial Estate, 0.9 miles to the west of Streatham Hill, brings panel joints and frame perimeters into the programme. For contractors at a college like St Francis Xavier Sixth Form College, 1.4 miles north-west of Streatham Hill, perimeters and internal sealant are timed for the holidays.

How we handle facade sealing in Streatham Hill
Managing agents and owners in Streatham Hill ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. We work on coping and flashing joints, shopfront frames and window and door perimeters, and the failures we are asked to look at most are failed sealant on precast panel joints and air leaks through failed facade joints. One point of contact handles commercial sealant work in Streatham Hill from the first photos to the final walk-round, whether it’s one building or several.
Every London site, Streatham Hill included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

How the quote is worked out
What shapes the price:
- The product specified
- Whether the work must be split into stages
- How much there is to seal
- Location, for remote and island sites
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Your programme or deadline
- Asbestos survey details if the building is older
- The product your specification calls for
- Anything awkward about access or site hours
For a fixed quote, phone 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. You can also send details through our quote form.
Common problems we fix in Streatham Hill
When the sealant tears down its centre, it has normally 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.
It’s worth sending us details if you spot any of the following:
- Draughts around frames and panels
- Perimeter joints where frames meet the structure
- Water coming in around window frames
- Gaps between rainscreen or cladding panels
New wings at hospitals like British Home & Hospital for Incurables, 1.4 miles to the south-east of Streatham Hill, bring long runs of window and panel joints to seal.

What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Specialist high-level access methods
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Damaged frames that need replacing
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Questions about Streatham Hill
Can work at a site such as King's College London fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. Suspect material is left alone until it has been tested.
Do you replace windows or glass?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months.
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. That is what makes the new joint last.
After the work
Keep the joints in good shape with a few simple steps:
- Confirm the survey covers external sealants in older buildings
- Plan facade sealing alongside redecoration
- Inspect facade joints on a regular cycle
- Avoid harsh cleaners on facade sealant
Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money.
Building owners, agents and FMs in Streatham Hill
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
From enquiry to sign-off
Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. 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.
- First we review photos, 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.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Getting the site ready
- Explain the parking and delivery arrangements
- Share your working hours and any access restrictions
- Clear stock, furniture or equipment away from the joints
