Construction mastic for commercial buildings in Hassell Street
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work so it helps to sequence elevations with some flexibility. Internal areas can usually carry on while the outside waits. Site teams most often ask us about frame gaps too wide for sealant alone and early adhesion failures on new external joints, across floor and skirting junctions, internal decorators’ caulk and cladding and panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Hassell Street it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Hassell Street, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the job changes by surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps so we will flag where the detail needs something different. Record requirements are agreed with the quote.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification, with backing rod in deeper gaps.
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Common questions from Hassell Street clients
Can the mastic package for our job in Hassell Street follow the site programme?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is hospital work, at somewhere like William Harvey 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.
What do you charge?
Each job is quoted on its own details. To get one, call the office on 01277 525 020 or email the details over.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Can you fit around our programme?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Rural sites near Hassell Street may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
What we need from you
- Share your working hours and any access restrictions
- Clear stock, furniture or equipment away from the joints
- Point out parking and an unloading spot

Construction mastic in Hassell Street: the local picture
At about 52 miles from central London, Hassell Street is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Hassell Street sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
New wings at hospitals like William Harvey Hospital (4.2 miles south-west of Hassell Street) bring long runs of window and panel joints to seal. When a school such as Wye School is extended or refurbished, the mastic package is often squeezed into the holidays.

What happens if it’s left?
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. Snagging can be priced as a separate stage. For buildings around smaller places like Hassell Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
There’s no price list, since every building and every scope is different. Call for a quote.

How the quote is worked out
Before we quote, we look at:
- Phasing around occupants
- Site requirements such as inductions and permits
- Removal of failed or old sealant
- Joint width, depth and condition
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Details that help us quote
To price the job accurately, we need a clear picture of the site. Send us:
- The asbestos register, for older buildings
- How the joints are reached, and at what height
- The postcode of the building
- Any specification or named product
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
