About our commercial sealant contractors in Great Shefford
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. We look before we quote and tell you plainly if sealant won’t solve it. Most enquiries involve a top-up bead over failed sealant, now lifting and untidy joints in a reception, shop floor or lobby, across kitchen worktops and splashbacks, floor and threshold joints and washrooms and tea points. A single leaking joint is often how a building in Great Shefford first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
The most common commercial job in Great Shefford is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.
Work in smaller places such as Great Shefford tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Deal with small splits before they become leaks
- Keep abrasive pads and scrapers off resealed joints
- Keep a record of which joints were resealed and when
- Keep washroom and kitchen extraction working
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are, so sound, smooth joints matter.

Common questions from Great Shefford clients
What site paperwork comes with a job in Great Shefford?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Is Great Shefford too far out for you?
Not at all. Great Shefford is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Could the old sealant in an older building contain asbestos?
We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder and removing it isn’t something we do.
How is commercial sealant work priced?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. 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.
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.
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.
Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For work around Great Shefford, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
Getting the site ready
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000
- Agree which areas must stay open

Why act early in Great Shefford
Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next. Resealing while only the sealant has failed keeps the job small. Older rural buildings around Great Shefford move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Commercial clients in Great Shefford
Building owners and managing agents use us on everything from one building to a spread of sites around Great Shefford. One quote can cover more than one site, so there’s one set of paperwork to deal with.
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.
Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
