How a job runs
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Work in places the size of Markyate is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Warn occupants and staff about the work
- Make sure the joints can be reached
- Have the specification and drawings to hand
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
Advice
Facade sealing for commercial buildings in Markyate
Facade sealants sit in the sun, rain and frost every day, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. We work on perimeter joints where frames meet the structure, stone and brick facade joints and cladding panel joints, and what we are called in for most is perimeter joints where frames meet the structure and previous reseals run over old sealant. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Markyate is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around places like Markyate, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What we’re called out for in Markyate
When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.
Typical triggers for a call:
- Previous reseals run over old sealant
- Staining on stone next to old sealant
- Leaks at window and door perimeters
- Gaps between rainscreen or cladding panels
New wings at hospitals like Luton and Dunstable Hospital, 4.1 miles north of Markyate, bring long runs of window and panel joints to seal.
What to look for in a quote
- How the joint faces will be prepared and primed
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will RAMS and insurance details be available?
- Their pre-qualification and accreditations
General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Why it’s worth doing now in Markyate
Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Small buildings around Markyate suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Facade sealing around Markyate: what changes locally
Markyate sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. The area within 2 miles of Markyate holds a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
For contractors at a school such as Markyate Village School and Nursery, sealing has to be finished before term starts. When units on a site such as Cotswold Business Park (1.5 miles north of Markyate) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Your questions answered
Can you work around term dates at a campus such as University Of Bedfordshire?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Cotswold Business Park, near Markyate, within your area?
Yes. Estates, retail parks and business parks around Markyate, Cotswold Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Do we need an asbestos check before resealing?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register. If asbestos is suspected, work stops until it is tested.
Do you run new sealant over the existing bead?
No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
