How we handle facade sealing in Borough Green
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. If you’re dealing with old perimeter mastic that has dried out and previous reseals run over old sealant, we can help, on coping and flashing joints, cladding panel joints and perimeter joints where frames meet the structure alike. Looking for mastic applicators who cover Borough Green? We’ve been sealing commercial buildings since 2005.
On a small site around Borough Green, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Share these points with them:
- Add perimeter sealant to planned maintenance checks
- Investigate damp beside windows promptly
- Keep pressure washers away from fresh sealant
- Avoid patch repairs on failed facade joints
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading.
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a job in Borough Green, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.
- 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.
- 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.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Tell staff and tenants when we’ll be in
- Explain the parking and delivery arrangements

Contractors’ notes for Borough Green
Several hotels sit less than 2 miles from Borough Green. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. Borough Green lies roughly 23 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
Hospital estates such as Sevenoaks Hospital (4.9 miles west of Borough Green) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Work at a hotel such as The Bull Hotel, 1.2 miles north of Borough Green, tends to be programmed around bookings, mastic included.
Borough Green is about 5 miles east of Sevenoaks, in Kent. We cover commercial sites throughout Borough Green, for single jobs and planned programmes alike. Borough Green is one of 931 places in Kent on our list for facade joints. Sites around London have their own page, about 23 miles away.

Borough Green: questions and answers
Is Borough Green too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is hospital work, at somewhere like Sevenoaks Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work while the building is occupied?
Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Do you replace windows or glass?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
What we are called out for in Borough Green
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back.
It’s worth sending us details if you spot any of the following:
- Hard, chalky sealant that no longer flexes
- Leaks at window and door perimeters
- Draughts around frames and panels
- Patch repairs that keep failing
Historic houses such as Old Soar Manor (2.1 miles south of Borough Green) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Before you book anyone
- How joint depth will be controlled
- The named product and why it was chosen
- What site paperwork they can supply
- Who will actually carry out the work
Surface by surface
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.
General trades versus a specialist
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.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
