Facade sealing in Charlton, done properly
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around. Site teams most often ask us about failed seals around shopfront and entrance frames and air leaks through failed facade joints, across shopfront frames, perimeter joints where frames meet the structure and coping and flashing joints. For commercial sealant work in Charlton, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places like Charlton, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job we finish is backed by a 12-month workmanship guarantee, in Charlton as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Why it’s worth doing now in Charlton
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts. Older rural buildings around Charlton move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
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.

Mastic packages on Charlton sites
Rainfall across the South East, Charlton included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Charlton is about 49 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.
For a contractor at a hotel such as Woodstock House Hotel, which lies north of Charlton, the mastic often has to be finished before a reopening date. When a school such as Singleton CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. For contractors at a college like West Dean College of Arts and Conservation, which lies west of Charlton, perimeters and internal sealant are timed for the holidays.

FAQs: Charlton
Will you plan work around the academic year at somewhere like University of Chichester?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Charlton too small for you to travel to?
No. Places such as Charlton are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you install glazing systems?
No. A glazing contractor handles that. What we seal are the joints around frames and panels.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Can staff carry on working while you are here?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Is colour matching possible?
It depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Aftercare for building managers
For the best life from the joints:
- Keep pressure washers away from fresh sealant
- Insist on a full cut-out when joints are renewed
- Keep sills, gutters and drainage paths clear
- Investigate damp beside windows promptly
Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.
Different surfaces, different methods
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex without tearing.
Coping and flashing joints
Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Site staff or a sealant specialist?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

From enquiry to sign-off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Charlton can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Before we start on site
- Let building users know which areas are affected
- Explain the parking and delivery arrangements
- Let us know about inductions and permits
