About our facade sealing in Charing Cross
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Where sealant is the specified fix, we also take on coping and flashing joints. Most enquiries involve sealant pulling away from frames or panels and hard, chalky sealant that no longer flexes, across cladding panel joints, coping and flashing joints and shopfront frames. A single leaking joint is often how a building in Charing Cross 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: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
Every job is signed 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.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Arranging specialist high-level access, which is planned with the client
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Joints too narrow for the movement they take, which need redesign
If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
Surfaces we seal
- Shopfront frames
- Window and door perimeters

After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Record the product and colour used on each elevation
- Share access with other external trades
- Brief window cleaners about newly sealed joints
- Don’t wait for a second leak before calling
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.
Signs you need facade sealing in Charing Cross
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained and rips when the facade moves.
Most enquiries start with something like this:
- Staining on stone next to old sealant
- Failed seals around shopfront and entrance frames
- Water coming in around window frames
- New sealant peeling off old mastic
Further education sites such as Westminster Kingsway College Soho Centre (to the north-west of Charing Cross) are extended and refurbished from time to time, with mastic often programmed into the summer break.

New build and refits around Charing Cross
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Charing Cross. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. A 2-mile radius around Charing Cross takes in a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Building work at universities like University of Notre Dame, less than half a mile to the north-west of Charing Cross, is often timed for the summer, mastic included. When units on a site such as Grand Vitesse Industrial Estate, 1.1 miles east of Charing Cross, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

What sets the cost
Before we quote, we look at:
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
- Removal of failed or old sealant
- The total length or number of joints
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- How the joints are reached, and at what height
- Whether an asbestos survey exists

On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Planning a London job such as one in Charing Cross 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.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Point out parking and an unloading spot
- Make sure the joints can be reached
- For older buildings, check the asbestos register before work

Questions about Charing Cross
Can you take on a job at a hospital such as St Thomas' Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them.
Can you fit around our working hours?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you seal facades in winter?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
