Facade sealing for commercial buildings in Shenington
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. We work on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure, and what we are called in for most is damp patches beside frames after rain and old perimeter mastic that has dried out. Most enquiries from Shenington start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a site near Shenington, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

FAQs: Shenington
Can you work around term dates at a campus such as Wroxton College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you work on a hospital site such as Horton General Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
How do we ask for a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or use the quote form. Include photos or drawings if you have them.
Do we need an asbestos check before resealing?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed. Removal of asbestos isn’t something we do.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
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 checks let you plan resealing before leaks or damage.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Arranging specialist high-level access, which is planned with the client
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Joints whose design needs changing by the specifier
If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think before you book.

Why deal with it now?
Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds. One visit to deal with every failing joint makes more sense than several trips to a place like Shenington. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Diagnose, treat, sign off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Shenington, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We start with photos, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.

After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Avoid patch repairs on failed facade joints
- Investigate damp beside windows promptly
- Check that rainwater leaves the facade the way it was designed to
- Brief window cleaners about newly sealed joints
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly.
Coordinate facade sealing with other external works. One set-up for several trades saves money and cuts time on site.
Building and refurbishing in Shenington
Rainfall across the South East, Shenington included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
Projects at schools like Shenington Church of England Primary School work to term dates, so mastic is programmed tightly. Hospital estates such as Horton General Hospital, 5.6 miles east of Shenington, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Historic houses such as Upton House (1.9 miles north of Shenington) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

General trades versus a specialist
Redoing a failed joint usually costs more than getting it right at the outset, 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.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
How the job changes by surface
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building, so preparation and product choice matter.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them to the correct depth.
