About our facade sealing in King's Walden
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces. If you are dealing with staining on stone next to old sealant and previous reseals run over old sealant, we can help, whatever the surface. One point of contact handles commercial sealant work in King's Walden from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Around smaller places like King's Walden, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:

- Arranging specialist high-level access, which is planned with the client
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.

Mastic packages on King's Walden sites
King's Walden lies roughly 29 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Rainfall across the South East, King's Walden included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
University estates such as University Of Bedfordshire (4.3 miles west of King's Walden) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. For contractors at a school such as Breachwood Green Junior Mixed and Infant School, sealing has to be finished before term starts. Historic houses such as Knebworth House, 4.7 miles south-east of King's Walden, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
King's Walden is about 4 miles south-west of Hitchin, in Hertfordshire. Our applicators travel to King's Walden for work on facade joints, handled exactly as we handle every other area.

Questions about King's Walden
Is hospital work, at somewhere like Lister Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Could you schedule work at a campus like University Of Bedfordshire for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Do you cover King's Walden?
Yes. We cover King's Walden, and you can ring 01277 525 020 or email us to get started.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
From enquiry to sign-off
Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. If others near King's Walden need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Share your working hours and any access restrictions
- Flag any permit to work we will need
- Point out any areas we must not close

Related advice
Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Keep the sealant details on the building file
- Add perimeter sealant to planned maintenance checks
- Share access with other external trades
- Don’t wait for a second leak before calling
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.
Coordinate facade sealing with other external works. One set-up for several trades saves money.
General trades versus a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
