Facade sealing for commercial buildings in Charvil
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. We work on stone and brick facade joints, coping and flashing joints and perimeter joints where frames meet the structure, and what we’re called in for most is unsightly perimeter sealant on a visible elevation and facade joints cracked through the middle. A specialist sealant contractor works differently from a general builder: on jobs in Charvil, preparation and product choice get the time they need.
For a contractor on a smaller site near Charvil, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
Every job we finish is backed by a 12-month workmanship guarantee, in Charvil as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Common questions from Charvil clients
Can you work at a site such as Loddon Vale Shopping Centre, by Charvil?
Yes. Estates, retail parks and business parks around Charvil, Loddon Vale Shopping Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Can you take on a job at a hospital such as Royal Berkshire Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you look at water coming in around a frame?
Yes. Photos help, and you can phone 01277 525 020 or email drawings and photos to arrange a visit. Failed perimeter sealant is a common cause, but not the only one.
What hours do you work?
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 we need an asbestos check before resealing?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, and we will ask to see it. Suspect material is left alone until it has been tested.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- The product specified
- How accessible the joints are
- Induction, permit and paperwork requirements
- Joint width, depth and condition
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- Asbestos survey details if the building is older
- When you need the work done
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available
For a fixed quote, ring 01277 525 020 or use the quote form with the site address and an outline of the work. You can also send details through our quote form.
Why deal with it now?
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. In a smaller place such as Charvil, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
What you get with us
- Joints cleaned back to sound surfaces
- A range of standard colours, depending on the product
- Products installed to the manufacturer’s instructions
- Colour agreed before work starts

Contractors’ notes for Charvil
There are several hotels within about 2 miles of Charvil. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Central London is about 34 miles from Charvil. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
New units and refits on sites such as Loddon Vale Shopping Centre, 1.5 miles south of Charvil, need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as Royal Berkshire Hospital, which lies south-west of Charvil, perimeter and facade sealing is planned around patients and deliveries. Work at a hotel such as The Great House Hotel, 1.2 miles west of Charvil, tends to be programmed around bookings, mastic included.

How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a site in Charvil, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

Advice
How the job changes by surface
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.
Render and coated surfaces
Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
