Construction mastic for commercial buildings in Gardeners Green
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. After that, the joints are prepared and sealed to the specification. If you are dealing with window and door perimeters that won’t pass inspection and perimeter gaps outside the sealant’s range, we can put it right, whatever the surface. Searching for sealant specialists in Gardeners Green? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Construction in and around smaller places such as Gardeners Green is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

New build and refits around Gardeners Green
Gardeners Green is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. There are a number of hotels within about 2 miles of Gardeners Green. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
School extensions, at buildings such as Saint Sebastians Church of England Primary School, usually run to the summer holidays, mastic included. New wings at hospitals like Wokingham Hospital, 1.8 miles to the north-west of Gardeners Green, bring long runs of window and panel joints to seal. When units on a site such as Molly Millars Lane Industrial Estate, 1.5 miles north-west of Gardeners Green, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Advice
Leave it or put it right?
Sealing over damaged or contaminated new joints might save a day. New sealant laid on old or dirty sealant has nothing to bond to. We cut out and redo the joint properly. One visit to deal with every failing joint makes more sense than several trips to a place like Gardeners Green. Send photos of each area and we’ll quote for the lot.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Gardeners Green: questions and answers
Could you schedule work at a campus like Newbold College of Higher Education for the vacation?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do you cover business parks and estates near Gardeners Green, such as Molly Millars Lane Industrial Estate?
Yes. Our area takes in Gardeners Green and its surroundings, with estates and business parks such as Molly Millars Lane Industrial Estate included. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Do you use the sealant named in the specification?
We work to the specification and the manufacturer’s installation guidance. Primers, backing and joint depth follow what the manufacturer sets out.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. We price to the specification and drawings.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Do you guarantee new-build sealant work?
Each package is backed by a 12-month guarantee. We carry five million pounds of public liability insurance.
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
How the job changes by surface
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. Done properly, it saves decorators time and gives a clean line.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Specifying the product where the designer hasn’t
- Deciding which fire-stopping product a penetration needs
- Frames fitted out of tolerance
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
