Expansion joint sealing for Andwell sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
On site: what to expect
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Andwell are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- 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.
What we need from you
- Tell us what induction or permit system the site runs
- Share your working hours and any access restrictions
- Send any specification or drawings in advance

Advice
Expansion joint sealing for commercial buildings in Andwell
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on blockwork control joints, precast concrete panel joints and podiums and floor movement joints, and what we are called in for most is spalled or broken joint edges in floors and decks and sealant pulling off the joint face. A single leaking joint is often how a building in Andwell first comes to us: we look at the rest while we’re there and tell you what we find.
Jobs around smaller places like Andwell are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

FAQs: Andwell
Would you work within a site like Basingstoke and North Hampshire Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Andwell off your patch?
No. Places such as Andwell are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Do you reseal car park expansion joints?
Yes. Let us know the opening hours and which levels or bays have to stay available.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Why has the sealant in our expansion joints split?
Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing.
For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
We work for building owners and managing agents on everything from one building to a spread of sites around Andwell. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Different surfaces, different methods
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces.
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit, with backing rod setting the depth.

Doing it in-house
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.
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 where general trades tend to cut corners.
Joints that move: notes for Andwell
Rainfall across the South East, Andwell included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. The 3 miles around Andwell take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Hospitals like Basingstoke and North Hampshire Hospital, 4.2 miles west of Andwell, have multi-storey or surface car parks whose joints carry vehicles round the clock. Another example is Chineham Court Business Park, which lies north-west of Andwell, where floors and yards would be done in stages around the occupiers.

What happens if it’s left?
Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex. Full removal and preparation is in every quote. Around Andwell, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why us?
- Clear, fixed quotes
- Work to your specification and the manufacturer’s guidance

Do you need expansion joint sealing in Andwell?
Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes.
Typical triggers for a call:
- New sealant over old, now failing
- Sealant peeling off one face of the joint
- Water getting into the wall through a failed joint
- Water dripping through deck or ramp joints
For an occupier at a site such as Hatch Industrial Park (0.8 miles south-west of Andwell), the joints at loading doors and dock levellers usually see the hardest wear.
