Commercial sealant contractors in Duns Tew
Pricing a commercial reseal is a short process. Our quote form takes photos, drawings or a schedule of the areas; you can also call the office on 01277 525 020 or email the details over with the details. Where the photos don’t tell the full story, we arrange a site visit. We work on washrooms and tea points, window and door perimeters and kitchen worktops and splashbacks, and the failures we are asked to look at most are black mould through washroom sealant that won’t clean off and expansion joints with the sealant torn out. A single leaking joint is often how a building in Duns Tew first comes to us: we look at the rest while we’re there and tell you what we find.
Quotes for commercial sealant in Duns Tew can come from photographs and a joint schedule, or from a walk-round, and the scope is set out in writing.
Rural business units near smaller places such as Duns Tew are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Roof leaks that only look like a joint problem
- Misted, cracked or failed glazing units (a glazier’s job)
- Cracking that needs a structural engineer to look at it
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
Where we work in Duns Tew

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For a building around Duns Tew, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
Before we start on site
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed

Advice
What happens if it’s left?
A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. In many cases the element is fine and only the seal around it has given up. Resealing usually costs far less than renewal. Halls, stores and units around places like Duns Tew may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Questions about Duns Tew
Is Duns Tew off your patch?
Not at all. Duns Tew is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Does your area include sites such as Hatch End Old Industrial Estate, near Duns Tew?
Yes. We cover Duns Tew and the area around it, including industrial estates, business parks and retail parks such as Hatch End Old Industrial Estate. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.
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: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Can you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
What about asbestos in old mastic?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.
Surface by surface
Fire-rated seals where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, so we’ll flag it if the detail needs a different product.
Commercial kitchens and tea points
Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing, with a food-safe or hygienic product wherever food contact can happen.

What else we do in Duns Tew
What sets the cost
Each job is priced on its own details. The main factors are:
- The total length or number of joints
- Distance, for remote addresses
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
Pricing sealant joints depends on quantities, condition and access, and any specification that applies. Call for a quote.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Any specification or named product
- Anything awkward about access or site hours
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Do you need commercial sealant contractors in Duns Tew?
If only one face has lost its grip, that’s an adhesion failure. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.
It’s worth sending us details if you spot any of the following:
- Gaps behind commercial kitchen worktops and sinks
- Wall and floor joints that have lost their seal
- Water staining near frames, panels or ceilings
- Messy, uneven beads from earlier work that let the building down
Offices and shops close to stations such as Heyford station, 2.8 miles to the south-east of Duns Tew, tend to be busy all day, so sealant work is planned around opening hours.
