Leave it or put it right?
The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Halls, stores and units around places like Clement Street may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

How we handle facade sealing in Clement Street
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, using sealants classified for facade or glazing use. If you are dealing with failed sealant on precast panel joints and perimeter sealant that has split or peeled away, we can put it right, on window and door perimeters, shopfront frames and perimeter joints where frames meet the structure alike. Searching for sealant specialists in Clement Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In the countryside around places like Clement Street, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to call us in Clement Street
When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.
Any of the following is a good reason to get the joints checked over:
- Air leaks through failed facade joints
- Perimeter joints where frames meet the structure
- Old perimeter mastic that has dried out
- Staining on stone next to old sealant
Hotel extensions and refits, at places such as Rowhill Grange Hotel & Utopia Spa (1 mile west of Clement Street), typically run between busy periods, so the sealing is squeezed into short windows.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- Their approach to joint depth and backing
- How they’ll work around occupants
- What site paperwork they can supply
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and we clear our waste as we work. Smaller jobs around Clement Street can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
What we need from you
- Have the specification and drawings to hand
- Agree which areas must stay open
- Explain the parking and delivery arrangements
Getting a fixed quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
Building and refurbishing in Clement Street
Clement Street sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Clement Street is about 14 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.
Recladding or extending a unit at a site like Button Street Business Park, 0.8 miles south of Clement Street, brings panel joints and frame perimeters into the programme. For contractors at a college like North Kent College, 1.4 miles north of Clement Street, perimeters and internal sealant are timed for the holidays.

General trades versus a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, 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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Clement Street: questions and answers
Is Clement Street too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Could you schedule work at a campus like University of Greenwich for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
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.
What will the job cost?
We don’t publish prices, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
Looking after the joints
For the best life from the joints:
- Plan facade sealing alongside redecoration
- Investigate damp beside windows promptly
- Confirm the survey covers external sealants in older buildings
- Keep the sealant details on the building file
Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones behind the facade.
What the job involves on each surface
Precast concrete panels
Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint rather than the system it surrounds.
