When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Water from a services leak rather than a joint
- Suspect materials that need testing and specialist removal
- Structural cracks or movement the joints weren’t designed for
If you are not sure, just ring 01277 525 020 or email the details over and we will give you a straight answer.
What we seal
- Washrooms and tea points
- Movement joints in walls and floors
- Floor and threshold joints
- Window and door perimeters
- External facade joints
- Kitchen worktops and splashbacks
Sealant applicators in Longparish
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure typically announces itself as a stained ceiling or an unhappy tenant. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on window and door perimeters, kitchen worktops and splashbacks and washrooms and tea points, and what we’re called in for most is layers of sealant, all of them failing and expansion joints with the sealant torn out. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Longparish, preparation and product choice get the time they need.
On a typical commercial building in Longparish, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Business units in the countryside around places like Longparish are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What we are called out for in Longparish
Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath so it soon peels and traps moisture against the joint. Getting back to a clean joint then means removing every layer.
It’s worth sending us details if you spot any of the following:
- A top-up bead over failed sealant, now lifting
- Greasy, split joints in a kitchen or tea point
- Untidy joints in a reception, shop floor or lobby
- Sanitary sealant that has gone black and patchy
For premises near Whitchurch (Hampshire) station, 3.5 miles north-east of Longparish, footfall is part of the plan: work is phased so shops and offices keep trading.

FAQs: Longparish
Is Harewood Forest Industrial Estate, near Longparish, within your area?
Yes. Our area takes in Longparish and its surroundings, with estates and business parks such as Harewood Forest Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Longparish outside your area?
Not at all. Longparish is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can areas stay open during the work?
Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.
Can you handle sealant work across several sites?
Yes, we can. Give us the sites and the scope at each, and we will put together a fixed quote and a sensible order of work.
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.
From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. If others near Longparish need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- 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.
Preparing the site
- Arrange parking or a loading space
- Share the asbestos register for older buildings
- Let us know about inductions and permits
Getting a fixed quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or use the quote form.

Working on commercial sites near Longparish
At about 59 miles from central London, Longparish is within reach of the capital. Business parks and retail centres are common around the capital’s motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings. The South East is one of the drier parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.
A unit on an estate like Harewood Forest Industrial Estate (to the south-west of Longparish) normally has an office front, a trade counter and staff facilities with joints of their own.
Longparish is about 5 miles east of Andover, in Hampshire. Any commercial site in Longparish is covered, for single jobs and planned programmes alike. Across Hampshire, 723 places are covered, Longparish among them. There’s a separate page for Southampton, about 19 miles away.

What’s near Longparish
Around Longparish, our work takes us to commercial buildings near The Cricketers Inn and the streets around them. The nearest railway station is Whitchurch (Hampshire) station, about 3.5 miles north-east of the centre. A little further out are Finkley Down Farm Museum (3.6 miles north-west) and Andover War Memorial Hospital (5.1 miles west). Not far away are Anton Lakes and Mill Lake.
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Keeping the joints sound
For the best life from the joints:
- Make sure ventilation in wet areas is switched on and working
- On pre-2000 buildings, share the asbestos information before work starts
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Keep a record of which joints were resealed and when
Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. If that happens, call the office on 01277 525 020 or email a schedule or drawings and we’ll price putting it right.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are.
