Our commercial sealant contractors service in Hampshire

We’ve applied sealant on commercial sites for over 20 years, and the paperwork side is in order: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. We work on floor and threshold joints, kitchen worktops and splashbacks and movement joints in walls and floors, and the failures we are asked to look at most are damp patches where an external joint has failed and movement joints packed with grit and debris.

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes part of a day on a small job and longer where several buildings or phases are involved.

You send photographs, drawings or a list of the joints and areas involved, or we arrange a site visit.
Next comes a diagnosis and a fixed quote.
We plan around your site hours and access windows, phasing the work where areas have to stay in use.
The failed bead is removed and the joint faces cleaned until they’re sound and dry.
Backing and primer go in where needed, then the chosen sealant is applied and tooled.
Each area is inspected, signed off and backed by our 12-month guarantee.

How we quote

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Commercial sealant contractors across Hampshire: the area picture

Across Hampshire, from Basingstoke, Winchester and Gosport to the smaller places between, commercial buildings run from high-street shops and offices to hotels, schools and business parks. We cover the whole area, so occupiers with several sites can use one contractor and one point of contact, with colours matched site to site where the brand needs it.

All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, so jobs in Hampshire are planned with access, loading and parking in mind. Coastal places in Hampshire often have hotels, guest houses and holiday accommodation with busy seasons, so work is often best planned for quieter months.

Basingstoke: Sites a few miles apart, such as Thornycroft Industrial Estate and West Ham Industrial Estate, can share one programme and one point of contact. A unit on an estate like Thornycroft Industrial Estate (to the south-west of Basingstoke) typically has an office front, a trade counter and staff facilities with joints of their own.

How the job changes by surface

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. Failed seals let grit and water in, and the edges start to suffer. The joints are resealed using a sealant matched to the movement and any traffic.

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. Access, such as scaffold already up, is agreed before the price is fixed.

Why deal with it now?

Sealant is often treated as an afterthought by the trade that fitted the element. Choosing the product, setting the depth and preparing the faces are what a specialist brings. You notice the difference years later, not on the day.

What your quote should include

Proof of insurance
How long is the guarantee, and what does it include?
Is depth set with backing rod, or bond-breaker tape in shallow joints?
Can the work be phased to keep areas open?

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

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. That’s why many clients bring in a specialist from the beginning.

Keeping the joints sound

Once the work is signed off, these steps help:

Ask fit-out and M&E contractors to report any sealant they disturb
Note dates and locations of sealant work for future planning
Don’t let cleaning or traffic back on before the cure time is up
Make sure ventilation in wet areas is switched on and working

Keep an eye out for other trades after we’ve gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed and the joint gets left open. If that happens, phone 01277 525 020 or use the quote form and we will price putting it right.

Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Hampshire can form part of a wider programme.

Hampshire: questions and answers

Can you take on work for an FM or managing agent?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

What site paperwork can you provide?

Let us know your requirements when you ask for a price. For older buildings we’ll ask for the asbestos register, plus your site induction rules.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Is your work guaranteed?

Our workmanship is guaranteed for 12 months. Public liability insurance is in place too.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
