Why act early in Marks Gate
Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once, which is often the biggest saving. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Facade sealing in Marks Gate
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. If you have new sealant peeling off old mastic and cladding panel joints that have opened up, we can help, whatever the surface. Most enquiries from Marks Gate start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Around Marks Gate, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

FAQs: Marks Gate
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Does your area include sites such as Grove Farm Retail Park, near Marks Gate?
Yes. Our area takes in Marks Gate and its surroundings, with estates and business parks such as Grove Farm Retail Park included. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Can staff carry on working while you’re here?
Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.
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.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep sills, gutters and drainage paths clear
- Keep pressure washers away from fresh sealant
- Don’t wait for a second leak before calling
- Plan facade sealing alongside redecoration
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant.
Coordinate facade sealing with other external works. One set-up for several trades saves money.
Surface by surface
Cladding panel joints
On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them to the correct depth.
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
How a job runs
Tell us your site hours and access windows and we’ll plan around them. 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 Marks Gate, 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 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.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- 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.
Preparing the site
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
- Tell us what induction or permit system the site runs

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Specialist high-level access methods
- Cracked or spalling substrates that need repair before sealing
- Work on the window or framing system itself
If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think.
What we seal
- Shopfront frames
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Cladding panel joints
- Stone and brick facade joints
- Window and door perimeters
Building and refurbishing in Marks Gate
Site traffic in Marks Gate falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in. The area within 2 miles of Marks Gate holds several hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
Projects at colleges like New City College (to the south-west of Marks Gate) tend to run to term dates, so the mastic is planned tightly. For contractors refurbishing units at places like Grove Farm Retail Park (1.9 miles south-west of Marks Gate), the mastic covers cladding panels, roller-door and window perimeters. With historic properties like Hare Hall, 2.8 miles to the east of Marks Gate, in the area, refurbishment work often meets old masonry that needs compatible sealants.
