Contractors’ notes for Hillstreet
The sea is no more than about 3 miles from Hillstreet. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Hillstreet 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 we time external mastic for dry faces and agree it with the site team.
Projects at schools like Calmore Junior School work to term dates, so mastic is programmed tightly. Further education sites such as Totton College (to the south of Hillstreet) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Construction mastic in Hillstreet, done properly
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place. Most enquiries involve missed perimeter joints on a new elevation and mastic snags holding up handover, on floor and skirting junctions, cladding and panel joints and brick and block movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Hillstreet it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a site near Hillstreet, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Ask installers to correct oversized gaps first
- Stick to the specified sealant rather than a generic substitute
- Keep scrapers and abrasive pads off new beads
- Share drawings and the specification as soon as possible
A new structure shifts as it loses construction moisture. The right product in each joint copes with that, but caulk in a joint that moves more than expected may crack. If that happens, let us know.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Related advice
Signs you need construction mastic in Hillstreet
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Choosing the right product for each joint reduces that.
Common reasons buildings call us in:
- Frame gaps too wide for sealant alone
- A long mastic snag list close to completion
- Bath and shower joints scraped during the final clean
- Inconsistent sealant finishes from plot to plot
Units on estates such as South Hampshire Industrial Park (to the south-east of Hillstreet) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What your quote should include
- How they’ll work around occupants
- Whether old or failed sealant will be cut out, not overlaid
- The terms of the workmanship guarantee
- What level of public liability insurance do they hold?
Questions we’re asked in Hillstreet
Can work at a site such as Totton College fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is a smaller place like Hillstreet outside your area?
No. Places such as Hillstreet are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
How do I request a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
What accreditations do you hold?
We are CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We’re fully insured for public liability.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you do fire-rated sealing on new builds?
Where it’s specified, yes. We will flag if the detail needs a different product.
Why act early in Hillstreet
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal. If the frame is life-expired, we’ll tell you. Older rural buildings around Hillstreet move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
