Facade sealing for commercial buildings in West Green
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. Site teams most often ask us about discoloured or dirty facade joints and air leaks through failed facade joints, on window and door perimeters, coping and flashing joints and perimeter joints where frames meet the structure. Looking for mastic applicators who cover West Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around places like West Green, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
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.

From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. What matters most for a job in West Green is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Getting the site ready
- Confirm the product named in the specification
- Let us know about inductions and permits
- Point out any areas we must not close

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Related advice
Site staff or a sealant specialist?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
New build and refits around West Green
The area within 2 miles of West Green holds plenty of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. West Green is about 26 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
New wings at hospitals like Crawley Hospital (0.5 miles south-west of West Green) bring long runs of window and panel joints to seal. School extensions, at buildings such as West Green Primary School, normally run to the summer holidays, mastic included.

Your questions answered
Is West Green too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Can you work at a site such as Crompton Fields Business Park, by West Green?
Yes, sites like Crompton Fields Business Park are within our area, along with the rest of West Green. Send details of the unit and the work through our quote form for a quick quote.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Should we check old sealant for asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Why deal with it now?
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Render or concrete edges that have broken away
- Providing access systems for the work
- Replacing glass or failed glazing units
If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.

What we are called out for in West Green
Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.
Clients typically get in touch after noticing one or more of the following:
- Staining on stone next to old sealant
- Damp patches beside frames after rain
- Failed seals around shopfront and entrance frames
- Cladding panel joints that have opened up
Recladding or extending a unit at a site like Crompton Fields Business Park, 0.5 miles to the north-east of West Green, brings panel joints and frame perimeters into the programme.
