About our commercial sealant contractors in Andover
Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind, and repeated splits in a movement joint can mean the joint is too narrow for the movement. Part of the job is telling you when the fix is something other than sealant. We work on external facade joints, floor and threshold joints and window and door perimeters, and what we are called in for most is water staining near frames, panels or ceilings and a top-up bead over failed sealant, now lifting. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Andover is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
On a typical commercial building in Andover, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Smaller commercial landlords and businesses in a town like Andover often have a handful of sealant jobs that can go on one visit: a frontage, a staff washroom, a kitchen and a few window perimeters, for example. One fixed quote then covers the lot.
A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or email us and we’ll arrange a return visit.

Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Act on the first lifting edges rather than waiting
- Check sealant as part of routine building inspections
- Keep a record of which joints were resealed and when
- Make sure contractors see the asbestos survey before cutting out old mastic
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.
Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.
Questions we are asked in Andover
Can you supply sealant in our brand colour for a site in Andover?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photos and we’ll confirm what’s available for the product.
Can you work at a site such as Northern Avenue Retail Park, by Andover?
Yes. We cover Andover and the area around it, including industrial estates, business parks and retail parks such as Northern Avenue Retail Park. A few photos and the unit address let us price the work.
Do you work directly for building managers?
Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.
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.
How is commercial sealant work priced?
The main factors are metres of joint, removal, access, the product and how many phases there are. For a fixed quote, send details through our quote form.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What guarantee do you give on resealing?
Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.
How the job changes by surface
Movement joints in walls and floors
A trafficked floor joint needs a different product from a wall joint. The choice comes down to how much the joint moves and what runs over it, and tell you if the edges need repairing first.
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. The design and sign-off of fire stopping belong to the designer and building control.
When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Roof leaks that only look like a joint problem
- Water from a services leak rather than a joint
If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

What else we do in Andover
Working on commercial sites near Andover
There are several hotels within about 2 miles of Andover. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, with rooms done in turn while the rest stay let. Rainfall across the South East, Andover included, is lower than in many parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.
A business with units at Northern Avenue Retail Park and Churchill Retail Park needn’t use two contractors for its sealant. For a retailer at a site such as Northern Avenue Retail Park, which lies north-east of Andover, the joints customers see are as much part of the fit-out as the shelving. Premises within reach of Andover station (0.5 miles west of Andover) often have busy frontages where joints are seen by everyone passing.
