Construction mastic for commercial buildings in Hollow Street
On a new build, the mastic package is one of the last trades through each area. Mastic Doctor takes on mastic packages for main contractors and developers with projects in Hollow Street, following the trades through the building as rooms and elevations become ready. We work on cladding and panel joints, floor and skirting junctions and brick and block movement joints, and the failures we are asked to look at most are mastic snags holding up handover and cracks opening in caulked internal joints. Whoever orders the work in Hollow Street, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions of older rural buildings near smaller places such as Hollow Street bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Contractors’ notes for Hollow Street
Rainfall across the South East, Hollow Street included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. At about 56 miles from central London, Hollow Street is within reach of the capital. 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.
Extensions at sites like St Martins Hospital (5.1 miles south-west of Hollow Street) usually sit beside working departments, and the mastic follows strict access rules. School extensions, at buildings such as Chislet Church of England Primary School, usually run to the summer holidays, mastic included. When units on a site such as Chislet Business Park, 1 mile south-west of Hollow Street, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Hollow Street is about 3 miles south-east of Herne Bay, in Kent. Anywhere in CT3, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

Different surfaces, different methods
Window and door perimeters

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product, food-safe where food contact is possible.
Common questions from Hollow Street clients
Is Chislet Business Park, near Hollow Street, within your area?
Yes, sites like Chislet Business Park are within our area, along with the rest of Hollow Street. A few photographs and the unit address let us price the work.
Is hospital work, at somewhere like St Martins Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Are you CHAS accredited?
Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. Public liability insurance of five million pounds is in place too.
Can fire-rated sealing at service penetrations be included?
We install fire-rated sealant where it is the specified product to the tested detail. We’ll flag if the detail needs a different product.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can you work plot by plot or floor by floor?
The programme sets the job. Share the release dates and we’ll match our work to them.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Specifying the product where the designer hasn’t
- Oversized gaps that need packing or adjustment by others
If you are not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
Joints and surfaces we work on
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Floor and skirting junctions
- Brick and block movement joints
- Cladding and panel joints
- Window and door perimeters
How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Distance, for remote addresses
- Joint width, depth and condition
- Phasing around occupants
- Access and working height
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
Sending details for a quote
Whether it’s one area or a whole building, these details speed things up:
- Your programme or deadline
- Approximate linear metres or a joint schedule
- Specification clauses that apply
- The site address and postcode
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email a schedule or drawings.
What happens if it’s left?
It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification. Called in at the end, the same issues surface during handover. Older rural buildings around Hollow Street move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
A quote for mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.
