Facade sealing in Crook Log
Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We plan for that and keep you updated. Most enquiries involve cladding panel joints that have opened up and weathered facade joints that have lost their grip, on coping and flashing joints, cladding panel joints and stone and brick facade joints. A specialist sealant contractor works differently from a general builder: in Crook Log, that means joint design, primers and backing rod as standard.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Surface by surface
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair first.
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints, not the framing or glazing itself.
Questions we’re asked in Crook Log
Does your area include sites such as Old Bexley Business Park, near Crook Log?
Yes. Our area takes in Crook Log and its surroundings, with estates and business parks such as Old Bexley Business Park included. Photos and a short description are enough for a first look.
Do you take on jobs in Crook Log where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
What will the job cost?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How the quote is worked out
To price the job, we consider:
- Joint width, depth and condition
- How accessible the joints are
- How much there is to seal
- Phasing around occupants
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Details that help us quote
To price the job accurately, we need to understand the site. Send us:
- A wide shot and a close-up of the area
- The site address and postcode
- When you need the work done
- Approximate linear metres or a joint schedule
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
When it isn’t the sealant
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Render or concrete edges that have broken away
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Joints too narrow for the movement they take, which need redesign
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
Surfaces we seal
- Cladding panel joints
- Window and door perimeters
- Stone and brick facade joints
- Shopfront frames
- Perimeter joints where frames meet the structure
- Coping and flashing joints
Why deal with it now?
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, which is often the biggest saving. Failed sealant in a building in Crook Log can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Facade sealing in Crook Log: the local picture
There are a number of hotels within about 2 miles of Crook Log. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Crook Log. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
Hotel extensions and refits, at places such as Bexleyheath Marriott Hotel, 1.2 miles to the east of Crook Log, typically run between busy periods, so the sealing is squeezed into short windows. Hospital estates such as Erith and District Hospital, 2.1 miles to the north-east of Crook Log, 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. University estates such as University of Greenwich Avery Hill Campus (2.3 miles south-west of Crook Log) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
Crook Log is about 3 miles south-east of Plumstead, in Greater London. We send applicators to Crook Log for facade joints. Crook Log is one of 764 places in Greater London on our list. Sites around London have their own page, roughly 10 miles from Crook Log.

From enquiry to sign-off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area.

Send the building rules and access times with your enquiry.
- We start with photos, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.

Advice
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Record the product and colour used on each elevation
- Never let anyone seal over old sealant
- Brief window cleaners about newly sealed joints
- Clear debris that holds water against joints
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.
