Facade sealing in Sonning
Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. We work on cladding panel joints, perimeter joints where frames meet the structure and stone and brick facade joints, and what we’re called in for most is perimeter joints where frames meet the structure and damp patches beside frames after rain. Most enquiries from Sonning 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.
Around smaller places like Sonning, building work typically 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.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Sonning: questions and answers
Is Sonning too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Is a hospital such as Royal Berkshire Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Do you replace windows or glass?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.
Can staff carry on working while you are here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Should we check old sealant for asbestos?
It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
Signs you need facade sealing in Sonning
Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.
Any of the following is a good reason to get the joints checked over:
- Gaps between rainscreen or cladding panels
- Damp patches beside frames after rain
- Perimeter sealant that has split or peeled away
- Cold air coming in at window perimeters
Recladding or extending a unit at a site like Loddon Vale Shopping Centre, 1.2 miles to the south-east of Sonning, brings panel joints and frame perimeters into the programme.

What happens if it’s left?
Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. For buildings around smaller places like Sonning, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

How a job runs
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs in and around smaller places like Sonning are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We start with photographs, 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.
- 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.
What we need from you
- Flag any permit to work we will need
- Send your site hours and access windows
- Point out parking and an unloading spot

Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
What the job involves on each surface
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.
Render and coated surfaces
Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Facade sealing around Sonning: what changes locally
A 2-mile radius around Sonning takes in several hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. Rainfall across the South East, Sonning included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.
New wings at hospitals like Royal Berkshire Hospital (2.6 miles south-west of Sonning) bring long runs of window and panel joints to seal.
