Facade sealing for commercial buildings in Clare Market
External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. We work on stone and brick facade joints, perimeter joints where frames meet the structure and window and door perimeters, and the failures we are asked to look at most are previous reseals run over old sealant and failed sealant on precast panel joints. Searching for sealant specialists in Clare Market? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Clare Market must meet its standards or pay the daily charge. Alongside that, sites normally need booked deliveries and a plan for where materials go.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What sets the cost
The price varies from site to site. It mainly depends on:
- The product specified
- The size and state of each joint
- How much there is to seal
- Working within restricted access windows
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What we need to price the job
It doesn’t need to be a full survey. These details are enough to start:
- The postcode of the building
- The product your specification calls for
- The asbestos register, for older buildings
- Whether the building will be occupied during the work
To get a fixed quote, speak to us on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. Our quote form is another easy route.
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Questions we are asked in Clare Market
Do you take on work at healthcare sites like Royal London Hospital for Integrated Medicine?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you cover business parks and estates near Clare Market, such as Grand Vitesse Industrial Estate?
Yes. We cover Clare Market and the area around it, including industrial estates, business parks and retail parks such as Grand Vitesse Industrial Estate. Photos and a short description are enough for a first look.
Which sealant do you use on facades?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can staff carry on working while you are here?
Typically, yes. We phase the work so most of the building stays in use.
Leave it or put it right?
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking a day or two for a few elevations, and longer where access has to be moved around the building. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Preparing the site
- For older buildings, check the asbestos register before work
- Make sure the joints can be reached
- Tell us what induction or permit system the site runs

When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Joints too narrow for the movement they take, which need redesign
- Damp caused by condensation inside the building
- Arranging specialist high-level access, which is planned with the client
If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think before you book.
Joints and surfaces we work on
- Cladding panel joints
- Shopfront frames
- Stone and brick facade joints
