Facade sealing in Great Chart, done properly
A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear. Most enquiries involve unsightly perimeter sealant on a visible elevation and cold air coming in at window perimeters, across cladding panel joints, coping and flashing joints and perimeter joints where frames meet the structure. Searching for sealant specialists in Great Chart? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Around smaller places like Great Chart, 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.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions we are asked in Great Chart
Is Great Chart off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Will you take on work at estates like St. Georges Business Centre, close to Great Chart?
Yes. We cover Great Chart and the area around it, including industrial estates, business parks and retail parks such as St. Georges Business Centre. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
How do we ask for a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you work in cold or wet weather?
Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we’ll set out a timescale with the quote.
From enquiry to sign-off
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Smaller jobs around Great Chart can be grouped with others nearby. 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.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Preparing the site
- For older buildings, check the asbestos register before work
- Confirm the product named in the specification
- Tell staff and tenants when we’ll be in

Why it’s worth doing now in Great Chart
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. For buildings around smaller places like Great Chart, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What you get with us

Cost factors for facade joints
To price the job, we consider:
- How accessible the joints are
- Induction, permit and paperwork requirements
- The total length or number of joints
- The product specified
A quote for facade joints depends on quantities, condition and access. Ask us for a fixed quote.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- Asbestos survey details if the building is older
- Clear photos of the problem areas
- Drawings or a marked-up plan, if available
- The type of building and who uses it
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Doing it in-house
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. That’s why many clients bring in a specialist from the beginning.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Building and refurbishing in Great Chart
Great Chart lies roughly 47 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Several hotels sit less than 2 miles from Great Chart. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Units on estates such as St. Georges Business Centre (to the north-east of Great Chart) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Older buildings in the area around Great Chart, such as Godinton House, 1.1 miles to the north of Great Chart, need care when sealed: the product has to suit soft or historic materials. Extensions at sites like William Harvey Hospital (to the east of Great Chart) usually sit beside working departments, and the mastic follows strict access rules.
