About facade sealing in City of London
We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. We work on perimeter joints where frames meet the structure, stone and brick facade joints and shopfront frames, and the usual reasons a site gets in touch are air leaks through failed facade joints and weathered facade joints that have lost their grip.
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Pricing in City of London
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Why choose Mastic Doctor
- Commercial sealant work since 2005
- Old sealant cut out, never sealed over

Facade sealing across City of London: the area picture
From Smithfield, Barbican Estate and Bishopsgate to smaller places across City of London, main contractors and developers need mastic packages for new build and refurbishment. We seal perimeters, facade joints and internal sealant to the specification, on programme.
The South East is one of the UK’s drier regions, though outside work in City of London still waits for dry faces, and cold mornings bring frost and condensation on steel and glass.
City of London: For contractors at a college like London College of Marketing and Technology, 0.9 miles east of City of London, perimeters and internal sealant are timed for the holidays. New units and refits on sites such as Southwark Bridge Business Centre (to the south of City of London) need their panel and perimeter joints sealed to the specification.
After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Inspect facade joints on a regular cycle
- Never let anyone seal over old sealant
- Keep the sealant details on the building file
- Keep sills, gutters and drainage paths clear
Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.
Coordinate facade sealing with other external works. One set-up for several trades saves money.
Why act early?
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure.
What your quote should include
- How the existing material will be dealt with
- Their pre-qualification and accreditations
- Their approach to joint depth and backing
- Will CSCS-carded applicators be on site?
Surface by surface
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, and mask the edges carefully.
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints, tooled to shed water.
General trades versus a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What affects the price in City of London
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Which sealant the job calls for
- Access and working height
- Phasing around occupants
- The site’s rules and procedures
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- How the joints are reached, and at what height
- The site address and postcode
- What the building is and how it’s used
- Clear photos of the problem areas
For a fixed quote, phone 01277 525 020 or email the details over, telling us the site location and the nature of the job. Our quote form is another easy route.
Common questions from City of London clients
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What will the job cost?
Each job is quoted on its own details. For yours, phone 01277 525 020 or email drawings and photos with a description of the work.
When can you be on site?
We’re 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.
What about RAMS and site documents?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
