Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Misted, cracked or failed glazing units (a glazier’s job)
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
Surfaces we seal
- External facade joints
- Movement joints in walls and floors
- Floor and threshold joints
- Washrooms and tea points
- Kitchen worktops and splashbacks
- Window and door perimeters
Commercial sealant contractors in Greatham
We’ve applied sealant on commercial sites for over 20 years: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. We work on kitchen worktops and splashbacks, window and door perimeters and floor and threshold joints, and the failures we’re asked to look at most are water staining near frames, panels or ceilings and earlier reseals applied straight onto the failed bead. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Greatham is the same: the right product in a properly prepared joint.
On a typical commercial building in Greatham, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
Commercial sealant work around smaller places like Greatham tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.
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.

Commercial premises in Greatham
Greatham is in the South East, one of the UK’s drier regions. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. The 3 miles around Greatham take in at least three named trading estates, business parks or retail parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal.
On a business park such as Longmoor Enterprise Park, less than half a mile north-east of Greatham, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. Offices and shops close to stations such as Liss station (to the south of Greatham) tend to be busy all day, so sealant work is planned around opening hours.
Greatham is about 5 miles north-east of Petersfield, in Hampshire. Anywhere in GU33, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Across Hampshire, 723 places are covered, Greatham among them. We also cover Portsmouth, some 20 miles away.
If you need commercial sealant contractors in GU33, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. We cover commercial and managed buildings on Longmoor Road, Wolfmere Lane and Todmore. Just outside Greatham, we also work in Longmoor (1 mile east), Woolmer (1 mile north), Liss Forest (1 mile south), Blackmoor (1 mile north) and The Mint (2 miles south).

When to call us in Greatham
A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. By the time it shows, there can be two or three layers to cut out.
Any of the following is a good reason to get the joints checked over:
- Messy, uneven beads from earlier work that let the building down
- Frame mastic that has hardened and come away from the wall
- Mouldy silicone around WCs, urinals and vanity tops
- Leaks that seem to come through a sealant line
A business with units at Longmoor Enterprise Park and Ham Barn Business Park needn’t use two contractors for its sealant.

General trades versus a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Questions we are asked in Greatham
Is Greatham off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Does your area include sites such as Longmoor Enterprise Park, near Greatham?

Are you CHAS accredited?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you take on work for an FM or managing agent?
Yes. You can send details through our quote form, and tell us what site paperwork you need.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Greatham are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- A final walk-round, then the 12-month guarantee applies.
Getting the site ready
- Share the asbestos register for older buildings
- Arrange parking or a loading space
- Tell staff and tenants when we’ll be in
Getting a fixed quote
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email the details over.
Advice
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Make sure contractors see the asbestos survey before cutting out old mastic
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Deal with small splits before they become leaks
- Ask fit-out and M&E contractors to report any sealant they disturb
Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet. Your maintenance team can look at extract fans at the same time.
Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.
