Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure for clients around Thrupp. Coping and flashing joints are included where sealant is the specified fix. Site teams most often ask us about new sealant peeling off old mastic and damp patches beside frames after rain, across stone and brick facade joints, coping and flashing joints and window and door perimeters. For commercial sealant work in Thrupp, you deal with one contact from quote to sign-off, whether it’s one building or several.

On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Thrupp are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- 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.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- 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.
Preparing the site
- Share the asbestos register for older buildings
- Let building users know which areas are affected
- Make sure the joints can be reached
Quotes
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Mastic packages on Thrupp sites
Central London is about 57 miles from Thrupp. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. A number of hotels sit less than 2 miles from Thrupp. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For contractors refurbishing units at places like Oxford Spires Business Park, 0.5 miles to the south-west of Thrupp, the mastic covers cladding panels, roller-door and window perimeters. For a contractor working at a hospital such as Acland Hospital (5.7 miles south of Thrupp), perimeter and facade sealing is planned around patients and deliveries.

What we are called out for in Thrupp
Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.
Things that normally lead to an enquiry:
- Weathered joints at frame-to-structure perimeters
- Water coming in around window frames
- New sealant peeling off old mastic
- Draughts around frames and panels
For contractors at a school such as The Marlborough Church of England School, sealing has to be finished before term starts.
Questions to ask before you book

- Will RAMS and insurance details be available?
- Their plan for phasing and protecting the area
- The named product and why it was chosen
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Damp caused by condensation inside the building
- Installing or repairing glazing systems
- Movement beyond what any sealant can handle
If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think.

Common questions from Thrupp clients
Do you cover business parks and estates near Thrupp, such as Oxford Spires Business Park?
Yes. Our area takes in Thrupp and its surroundings, with estates and business parks such as Oxford Spires Business Park included. Photos and a short description are enough for a first look.
Can you work on a hospital site such as Acland Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Do you replace windows or glass?
No. That work needs a glazing specialist. What we seal are the joints around frames and panels across the facade.
Is it okay to overlay old mastic?
No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Cost factors for facade joints
To price the job, we consider:
- Travel to remote or island sites
- Backing rod, priming and other preparation
- The site’s rules and procedures
- Any access equipment needed
Pricing facade joints depends on quantities, condition and access. Call for a quote.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- Asbestos survey details if the building is older
- Rough lengths or quantities, or drawings if you have them
- The site address and postcode
- Photos of the joints, close up and from further back
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or email us.
Leave it or put it right?
Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. For buildings around smaller places like Thrupp, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
