Expansion joint sealing in Wherwell Wood: the local picture
Wherwell Wood is about 63 miles from central London. Warehousing clusters around the motorways that ring and radiate from London. Wherwell Wood sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.
Hospital campuses such as Andover War Memorial Hospital, 3.2 miles north-west of Wherwell Wood, grow in stages, leaving movement joints wherever new blocks meet old. Across sites such as Anton Business Park, 2.3 miles to the north-west of Wherwell Wood, floor and movement joints can be sealed in phases so units keep working. On industrial estates such as Harewood Forest Industrial Estate (2.2 miles east of Wherwell Wood), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
Wherwell Wood is about 3 miles south-east of Andover, in Hampshire. Businesses, contractors and managing agents in Wherwell Wood can call on us for movement joints, as part of our coverage of Hampshire. We work across 723 places in Hampshire.

How we handle expansion joint sealing in Wherwell Wood
The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. The enquiries we see most involve spalled or broken joint edges in floors and decks and previous reseals laid over old sealant, across brickwork movement joints, cladding panel joints and blockwork control joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Wherwell Wood it comes down to the same thing: the right product in a properly prepared joint.
In and around smaller places like Wherwell Wood, 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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

FAQs: Wherwell Wood
Can you take on a job at a hospital such as Andover War Memorial Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Wherwell Wood too small for you to travel to?
Not at all. Wherwell Wood is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
What if the joint edges are damaged?
Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we’ll say so when we quote.
Cost factors for movement joints
A fixed quote reflects the actual work. It takes account of:
- Joint width, depth and condition
- Working within restricted access windows
- Site requirements such as inductions and permits
- How accessible the joints are
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Sending details for a quote
Whether it’s one area or a whole building, the same details help:
- Clear photographs of the problem areas
- Drawings or a marked-up plan, if available
- Your programme or deadline
- Asbestos survey details if the building is older
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or send details through our quote form.
Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
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.

After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Keep traffic off new joints until the cure time is up
- Keep racking legs and heavy point loads off floor joints
- Look over external and deck joints after a hard winter
- Treat a small split as a warning, not a cosmetic issue
Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint. Barriers left in place until then protect the finish.
Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one. We’ll tell you which movement joints need doing now and which can wait.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Leaks coming from the membrane rather than the joint seal
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Crumbling edges that would give a new bead nothing sound to grip
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Wherwell Wood can be grouped with others nearby. You’ll have a fixed quote before work starts.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Have the specification and drawings to hand
- Make sure the joints can be reached
