Commercial clients in Steventon
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Steventon can form part of a wider programme across Oxfordshire.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Construction mastic in Steventon, done properly
Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal areas can usually carry on while the outside waits. We work on brick and block movement joints, window and door perimeters and internal decorators’ caulk, and the failures we’re asked to look at most are sealant knocked or painted over by other trades and oversized or tapered gaps around new frames. Most enquiries from Steventon 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.
Conversions of older rural buildings near smaller places such as Steventon bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Questions we are asked in Steventon
Does your area include sites such as The Core Business Centre, near Steventon?
Yes, sites like The Core Business Centre are within our area, along with the rest of Steventon. A few photos and the unit address let us price the work.
Is hospital work, at somewhere like Abingdon Community Hospital, something you do?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Does weather affect external mastic work?
Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing.
Do you use the sealant named in the specification?
We follow the specified sealant and flag anything that doesn’t look right for the joint. Specifications often reference BS EN 15651 or BS 6213.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Signs you need construction mastic in Steventon
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond, so preparation matters as much here as on a reseal.
Clients typically get in touch after noticing one or more of the following:
- A mastic package split between trades with no clear owner
- Cracks opening in caulked internal joints
- A long mastic snag list close to completion
- Bath and shower joints scraped during the final clean
For a contractor at a hotel such as Steventon House Hotel, which lies south-east of Steventon, the mastic often has to be finished before a reopening date.
What your quote should include
- Will failed sealant be removed rather than covered?
- The named product and why it was chosen
- Will RAMS and insurance details be available?
- How they’ll work around occupants
Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Don’t schedule sealing before decorators and flooring are done
- Stick to the specified sealant rather than a generic substitute
- Ask for joint and product checks before the package is urgent
- Ask installers to correct oversized gaps first
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known. Tell us what records you need and we will confirm with the quote.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors. Getting the product and preparation right first time avoids that.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Rework caused by others damaging completed areas
- Joint design decisions that belong to the architect or engineer
If in doubt, call 01277 525 020 or send photos by email and we will say what we think before you book.
What we seal
- Floor and skirting junctions
- Sanitary and kitchen joints
- Brick and block movement joints
- Internal decorators’ caulk
- Cladding and panel joints
- Window and door perimeters

For contractors refurbishing units at places like The Core Business Centre, 0.9 miles south-east of Steventon, the mastic covers cladding panels, roller-door and window perimeters.
