Construction mastic for commercial buildings in Kent Street
We work to the specification and the programme. If a product is named, that’s what goes in, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out. If you are dealing with a mastic package split between trades with no clear owner and snag items on joints that need redoing before handover, we can put it right. Looking for mastic applicators who cover Kent Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Construction in and around smaller places such as Kent Street is often barn conversions, small groups of houses or extensions to halls and schools. 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 Kent Street as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Work for main contractors and building owners
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
We work for building owners and managing agents on everything from one building to a spread of sites around Kent Street. One quote can cover more than one site, which keeps the paperwork simple.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Protect sealed areas from following trades
- Release areas for mastic once other trades have finished in them
- Ask installers to correct oversized gaps first
- Share drawings and the specification as soon as possible
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
Different surfaces, different methods
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps, and we’ll tell you if the detail calls for something else. Tell us what records you need and we will confirm with the quote.

- Frames fitted out of tolerance
- Defective windows, doors or glazing units (the supplier or installer’s job)

What we’re called out for in Kent Street
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Common reasons buildings call us in:
- Cracks opening in caulked internal joints
- Inconsistent sealant finishes from plot to plot
- Frame perimeters left unsealed or poorly sealed
- External joints sealed in damp or cold conditions that are now failing
For contractors refurbishing units at places like Oakendene Industrial Estate, 0.8 miles north of Kent Street, the mastic covers cladding panels, roller-door and window perimeters.

Facades, frames and programmes in Kent Street
Kent Street sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. At about 37 miles from central London, Kent Street is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
On a healthcare site such as The Dene Hospital, 3.8 miles east of Kent Street, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Questions we are asked in Kent Street
Is hospital work, at somewhere like The Dene Hospital, something you do?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Is Kent Street too far out for you?
No. Places such as Kent Street 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.
Can you work plot by plot or floor by floor?
We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
