Chilbolton: questions and answers
Can you work on a hospital site such as Andover War Memorial Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Does your area include sites such as Harewood Forest Industrial Estate, near Chilbolton?
Yes, sites like Harewood Forest Industrial Estate are within our area, along with the rest of Chilbolton. Photos and a short description are enough for a first look.
What timescale should we allow for resealing expansion joints?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.
Do you cover Chilbolton?
Yes. We take on work across Chilbolton, and the same phone number covers every area.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you work to our specification?
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.
What happens if it rains on the day?
A wet joint can’t be sealed properly. The work is simply moved to the next suitable day.
Expansion joint sealing in Chilbolton, done properly
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors. If you’re dealing with spalled or broken joint edges in floors and decks and brittle, chalky sealant on external joints, we can put it right, on cladding panel joints, podiums and floor movement joints and precast concrete panel joints alike. Looking for mastic applicators who cover Chilbolton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In and around smaller places like Chilbolton, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Keeping the joints sound
To get the most from the new sealant:
- Reopen bays and walkways only after the stated cure time
- Look over external and deck joints after a hard winter
- Clear dirt from joint lines during routine cleaning
- Treat a small split as a warning, not a cosmetic issue
Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it. A routine sweep is the simplest protection.
Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load. Keeping the seal sound avoids all of that.
Different surfaces, different methods
Cladding panel joints
We confirm what access is in place before pricing. Close-up photos help us judge the joints, or we visit if they don’t show enough.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.
Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and our waste is bagged and taken away as we go. If others near Chilbolton need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Warn occupants and staff about the work
- Send any specification or drawings in advance

Advice
Warehouse floors and decks around Chilbolton
Chilbolton sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in. Central London is about 63 miles from Chilbolton. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.
Sites like Andover War Memorial Hospital (to the north-west of Chilbolton) carry ambulances, deliveries and visitors’ cars over their road and deck joints. Schools such as Wherwell Primary School have movement joints in their walls and floors that are easy to overlook. Warehouse floors on estates like Harewood Forest Industrial Estate, 2.6 miles to the north-east of Chilbolton, carry pallet trucks and forklifts over every saw-cut joint.

Why act early in Chilbolton
Doing joint resealing alongside other planned works can save on access. But joints already letting water in shouldn’t wait for a programme, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. Halls, stores and units around places like Chilbolton 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.
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.

When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Joints too narrow for the movement, which need redesigning by the engineer
