Working on commercial sites near Wherwell
Wherwell is about 63 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. If you have premises across the region, one contractor can cover them all. Rainfall across the South East, Wherwell included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.
On estates like Harewood Forest Industrial Estate, which lies north-east of Wherwell, the office and welfare end of each unit has its own sealant to maintain.
Wherwell is about 3 miles south-east of Andover, in Hampshire. Businesses, contractors and managing agents in Wherwell can call on us for sealant joints, as part of our coverage of Hampshire.

Commercial mastic work in Wherwell

For sites in Wherwell, the quickest start is to call the office on 01277 525 020 or email drawings and photos with a list of addresses. The enquiries we see most involve gaps behind commercial kitchen worktops and sinks and frame sealant that has cracked, shrunk or pulled away, across movement joints in walls and floors, washrooms and tea points and external facade joints. Searching for sealant specialists in Wherwell? We’ve been sealing commercial buildings since 2005.
In Wherwell, as anywhere, the first joints to go are normally the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.
Commercial sealant work around smaller places like Wherwell tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.
Our workmanship is guaranteed for 12 months, in Wherwell as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What the job involves on each surface
Shop fronts and retail fit-outs
Retail work usually has to fit around trading. We plan around the access windows the store gives us, phasing areas so the shop floor stays usable.
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services.
What happens if it’s left?
Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation. You notice the difference years later, not on the day. One visit to deal with every failing joint makes more sense than several trips to a place like Wherwell, rather than one at a time. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Signs you need commercial sealant contractors in Wherwell
No sealant joint is permanent. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. On a busy commercial site several of those pile up at once, which is why regular inspection pays.
It’s worth sending us details if you spot any of the following:
- A top-up bead over failed sealant, now lifting
- Shrunken sealant along kitchen worktops and splashbacks
- Smeared sealant across finishes from a rushed job
- Frame sealant that has cracked, shrunk or pulled away
Offices and shops close to stations such as Andover station (to the north-west of Wherwell) tend to be busy all day, so sealant work is planned around opening hours.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- The terms of the workmanship guarantee
- The named product and why it was chosen
- How the joint faces will be prepared and primed
Your questions answered
Is a smaller place like Wherwell outside your area?
Not at all. Wherwell is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Will you take on work at estates like Harewood Forest Industrial Estate, close to Wherwell?
Yes, sites like Harewood Forest Industrial Estate are within our area, along with the rest of Wherwell. To start, just call the office on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What do you need from us to quote?
Photos, drawings or a schedule of the joints are usually enough to start through the quote form on this site. If a visit is needed we will book one, and a fixed quote follows.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Will the building have to shut during the work?
We phase the work so parts of the building stay open. We plan around the site hours and access windows you give us.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Keep barriers up until the new sealant has cured
- Add sealant to the planned maintenance inspection list
- Check joints after other trades have worked nearby
- Brief cleaning contractors to avoid scourers and blades on sealant
We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.
Sealant installed at the same time usually fails in sequence. The first failures are often a warning about the rest so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.
From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. Smaller jobs around Wherwell can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- You send photos, drawings or a list of the joints and areas involved, or we arrange a site visit.
- We work out why the joints have failed and fix a quote for the agreed scope.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- We strip the failed bead and prepare both faces of the joint.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
What we need from you
- Send any specification or drawings in advance
- Let us know about inductions and permits
- Explain the parking and delivery arrangements
