Shops, offices and hotels in and around Lower Upham
The 3 miles around Lower Upham take in at least three named trading estates, business parks or retail parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints. Lower Upham is in the South East, one of the UK’s drier regions. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.
If you run a unit on an estate such as Deer Park Farm Industrial Estate (1.6 miles south-west of Lower Upham), the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Offices and shops close to stations such as Hedge End station, 3.4 miles to the south-west of Lower Upham, tend to be busy all day, so sealant work is planned around opening hours.

Commercial mastic work in Lower Upham
If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Lower Upham, call 01277 525 020 or email drawings and photos with the site addresses. If you have wall and floor joints that have lost their seal and messy, uneven beads from earlier work that let the building down, we can help, on window and door perimeters, movement joints in walls and floors and kitchen worktops and splashbacks alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Lower Upham, that means joint design, primers and backing rod as standard.
On a typical commercial building in Lower Upham, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
In and around smaller places such as Lower Upham, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common problems we fix in Lower Upham
Outside, sunlight and rain wear sealant down year after year. Sunny elevations dry the surface out and exposed ones take driving rain, so beads chalk, stiffen and lose their stretch. Once it stiffens, the joint opens up at the next big temperature swing.
Common reasons buildings call us in:
- External beads that have gone brittle and cracked
- Damp patches where an external joint has failed
- Window and door perimeter joints that have cracked open
- Black mould through washroom sealant that won’t clean off
If you have premises on more than one site, say at Deer Park Farm Industrial Estate and Vicarage Farm Business Park, one contractor and one quote can cover both.
What to look for in a quote
- Whether old or failed sealant will be cut out, not overlaid
- The named product and why it was chosen
- Their pre-qualification and accreditations
- What level of public liability insurance do they hold?
Maintenance after handover
For the best life from the joints:
- Check the asbestos register before anyone disturbs old sealant in an older building
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Keep barriers up until the new sealant has cured
- Ask fit-out and M&E contractors to report any sealant they disturb
New joints need their full cure time before they take water, cleaning or traffic. Cure time varies with the product, conditions and depth of the joint, and we confirm it when each area is handed back. Keeping signs or barriers up until then protects the finish.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to, which makes sound joints worth keeping on top of.
Owners, agents and contractors
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Leave it or put it right?
Putting off a reseal usually moves the cost rather than avoiding it. Once water gets behind the seal, finishes and ceilings underneath are next. Resealing while only the sealant has failed keeps the job small. One visit to deal with every failing joint makes more sense than several trips to a place like Lower Upham, rather than one at a time. Photos of every joint help us quote for the whole job.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Lower Upham are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.

Advice
Different surfaces, different methods
Commercial kitchens and tea points
Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. Proper degreasing comes before any new sealant.
Window and door perimeters
Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. The product depends on whether the joint will be painted, in a shade that suits the frame.
Lower Upham: questions and answers
Do you offer colour-matched sealant for buildings in Lower Upham?
Yes, we can typically get close to most finishes from the product’s colour range. Send colour references or photographs and we will confirm what’s available for the product.
Can you work at a site such as Deer Park Farm Industrial Estate, by Lower Upham?
Yes, sites like Deer Park Farm Industrial Estate are within our area, along with the rest of Lower Upham. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Could the old sealant in an older building contain asbestos?
It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
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.
How long does a job like this take?
That varies with the scale of the job, but the work usually takes a few hours for one area, or a planned series of visits across a bigger building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
How do we get a quote?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.
