Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- The site’s rules and procedures
- How accessible the joints are
- Whether the work must be split into stages
- Removal of failed or old sealant
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Rough lengths or quantities, or drawings if you have them
- The product your specification calls for
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
Construction mastic for commercial buildings in Hawthorn
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up so it helps to sequence elevations with some flexibility. Internal areas can normally carry on while the outside waits. Site teams most often ask us about a mastic package split between trades with no clear owner and new external sealant already peeling away, across sanitary and kitchen joints, cladding and panel joints and floor and skirting junctions. Searching for sealant specialists in Hawthorn? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Conversions of older rural buildings near smaller places such as Hawthorn 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 sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Building and refurbishing in Hawthorn
The sea is no more than about 2 miles from Hawthorn. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. Hawthorn sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
New units and refits on sites such as Eddington Business Park (2.2 miles west of Hawthorn) need their panel and perimeter joints sealed to the specification. School extensions, at buildings such as Reculver Church of England Primary School, typically run to the summer holidays, mastic included. Extensions at sites like Queen Victoria Memorial Hospital, 1.4 miles to the west of Hawthorn, typically sit beside working departments, and the mastic follows strict access rules.

Why deal with it now?
Sealing over damaged or contaminated new joints might save a day. Sealant can’t grip a contaminated or existing bead. Damaged joints are removed and resealed from clean faces. Converted and older buildings near places like Hawthorn tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Why appoint us
- Colours confirmed for the specified product
- Constructionline member for supplier checks
- 12-month guarantee on workmanship
- A fixed quote before work starts
See our cost guide or our accreditations.
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Ask for joint and product checks before the package is urgent
- Plan external elevations with the weather in mind
- Keep scrapers and abrasive pads off new beads
- Keep finished joints away from paint, plaster and scrapers
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later. Tell us what records you need and we’ll confirm with the quote.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out, and avoids a rush.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Joint design decisions that belong to the architect or engineer
- Oversized gaps that need packing or adjustment by others
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer.
