Facade sealing in Hither Green, done properly
Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We build that into the programme and tell you if the forecast changes the plan. We work on coping and flashing joints, cladding panel joints and perimeter joints where frames meet the structure, and what we’re called in for most is draughts around frames and panels and gaps between rainscreen or cladding panels. A single leaking joint is often how a building in Hither Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Questions we are asked in Hither Green
Is hospital work, at somewhere like University Hospital Lewisham, something you do?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you take on jobs in Hither Green where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can you find out why a window is leaking?
Yes. Photos help, and you can call the office on 01277 525 020 or email us to arrange a visit. Many frame leaks are sealant failures, though not all, and we’ll be honest about which it is.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Will rain stop the work?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things.
What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Render or concrete edges that have broken away
- Providing access systems for the work
- Installing or repairing glazing systems
Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Planning a London job such as one in Hither Green starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- First we review photos, 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.
What we need from you
- Share the asbestos register for older buildings
- Agree which areas must stay open
- Arrange parking or a loading space

Cost factors for facade joints
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
- The total length or number of joints
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- A wide shot and a close-up of the area
- How the joints are reached, and at what height
- What the building is and how it’s used
- The asbestos register, for older buildings
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email us.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Doing it in-house
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Surface by surface
Window and door perimeters
Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus neutral-cure product, chosen for the frame and wall, goes in, tooled to shed water.
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface.
New build and refits around Hither Green
Hither Green has a good number of hotels close by, all within 2 miles. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. The ULEZ covers the whole of Greater London, Hither Green included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
For contractors at a college like Christ the King Sixth Form College (0.9 miles north of Hither Green), perimeters and internal sealant are timed for the holidays. Hospital estates such as University Hospital Lewisham, 0.8 miles to the west of Hither Green, 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. For a contractor at a hotel such as St Wolframs Hotel, 1 mile north of Hither Green, the mastic often has to be finished before a reopening date.
