How a job runs
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Getting the site ready
- Send your site hours and access windows
- Explain the parking and delivery arrangements
- Make sure the joints can be reached
Ask for a quote
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or send photos by email.

How we handle mastic sealing in Paddington
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. If you have draughts at frames across a block and estate-wide sealant that is simply worn out, we can put it right, whatever the surface. Most enquiries from Paddington start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Across Greater London, Paddington included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Joint width, depth and condition
- The site’s rules and procedures
- The total length or number of joints
- Travel to remote or island sites
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Your programme or deadline
- Specification clauses that apply
- The site address and postcode
- Asbestos survey details if the building is older
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
What we’re called out for in Paddington
The edges of the material itself sometimes break away for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Look out for the following:
- Damp patches beside frames
- Draught complaints from residents or tenants
- No planned programme for sealant
- Window mastic that has split and shrunk
Owners of student blocks near Imperial College London, less than half a mile north of Paddington, can schedule frame and external mastic for the summer vacation.
Comparing quotes
- Is the sealant right for the movement and the substrate?
- Will CSCS-carded applicators be on site?
- What level of public liability insurance do they hold?
- Will failed sealant be removed rather than covered?
When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Asbestos-containing sealant, which we don’t remove
- Broken glass or failed sealed units
If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think before you book.
What we seal
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- External wall and movement joints
- Balcony and threshold joints
- Communal kitchens and washrooms
For managing agents and facilities managers
Building owners and managing agents use us on everything from one building to a spread of sites around Paddington. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Questions we’re asked in Paddington
Does your area include sites such as Brompton Cross District Shopping Centre., near Paddington?
Yes. We cover Paddington and the area around it, including industrial estates, business parks and retail parks such as Brompton Cross District Shopping Centre.. A few photographs and the unit address let us price the work.
Do you work for managing agents with blocks near London Paddington station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
Is Paddington in your area?
Yes. We cover Paddington, and the simplest way to start is to give us a call on 01277 525 020 or send details through our quote form.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Who decides which product is used?
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.
Do you work for managing agents and housing associations?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.

Why deal with it now?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
