About our coloured sealant in Blackhill
Colour-matched joints are often among the last items before handover. Adjacent finishes are masked and protected while we work, and snag any marks before we leave. Our workmanship carries a 12-month guarantee. Site teams most often ask us about smeared sealant on stone or joinery and old sealant that has yellowed, darkened or faded, on powder-coated and anodised frames, cladding panels and office fit-out finishes. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Blackhill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Business units in the countryside around places like Blackhill are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What the job involves on each surface
Cladding panels
Panel joints form a grid on the facade, so colour matters. We pick a facade-grade sealant in a shade that sits with the panels, rated for the joint’s movement.
Hotel interiors
Phased work can be planned so areas stay in use. We plan around your occupancy so rooms return to service in stages.

Commercial premises in Blackhill
Blackhill sits in one of the drier corners of the country, the South East. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. The 3 miles around Blackhill take in at least three named trading estates, business parks or retail parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints; brand colours often come into it.
If you run a unit on an estate such as Shelley Farm Industrial Estate (1.3 miles east of Blackhill), the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Sites a few miles apart, such as Shelley Farm Industrial Estate and Mortimer Trading Estate, can share one programme and one point of contact.

Questions we are asked in Blackhill
Do you cover business parks and estates near Blackhill, such as Shelley Farm Industrial Estate?
Yes. Estates, retail parks and business parks around Blackhill, Shelley Farm Industrial Estate among them, are all within reach. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Can you supply sealant in our brand colour for a site in Blackhill?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Do you cover Blackhill?
Yes. Blackhill falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or use the quote form.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Why act early in Blackhill
Agreeing the colour before work starts avoids paying twice. A sample takes little time. Halls, stores and units around places like Blackhill may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
A quote for colour-matched joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

For managing agents and facilities managers
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Materials with mixed tones that defy a single match
- A guaranteed perfect match to every finish
- Overpainting a joint that needs a non-paintable product

Common problems we fix in Blackhill
Exposure takes its toll on colour. UV, grime and weathering alter how a bead looks after a few years. Resealing is the chance to reset the colour.
Site and facilities staff are often the first to spot these:
- Patch repairs in several different colours
- Shop fits that need consistent sealant colours across sites
- Old colour-matched joints lifting at the edges
- White or grey sealant that clashes with the finish
Shops and cafés around stations like Romsey station, 4 miles to the north-east of Blackhill, trade from early, so work is timed around them.
