Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Combine resealing with other works that need access
- Add perimeter sealant to planned maintenance checks
- Note when each elevation was last resealed
- Brief window cleaners about newly sealed joints
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.
Facade sealing for commercial buildings in Greywell
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. Most enquiries involve patch repairs that keep failing and perimeter sealant that has split or peeled away, across cladding panel joints, coping and flashing joints and shopfront frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Greywell, that means joint design, primers and backing rod as standard.
Sites around smaller places like Greywell can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we will quote to suit.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Mastic packages on Greywell sites
Greywell lies roughly 41 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Rainfall across the South East, Greywell included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
Hotel extensions and refits, at places such as Basingstoke Country Hotel, 1.2 miles to the north-west of Greywell, typically run between busy periods, so the sealing is squeezed into short windows. For contractors at a school such as Robert May's School, sealing has to be finished before term starts. New units and refits on sites such as Murrell Green Business Park (to the north-east of Greywell) need their panel and perimeter joints sealed to the specification.
Greywell is about 6 miles east of Basingstoke, in Hampshire. We cover Greywell, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Hampshire, 723 places are covered, Greywell among them. Sites around Reading have their own page, roughly 13 miles from Greywell.

How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Greywell, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.

How the job changes by surface
Precast concrete panels
Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex without tearing.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Damp caused by condensation inside the building
- Joints whose design needs changing by the specifier
- Cracked or spalling substrates that need repair before sealing
If you are not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Leave it or put it right?
Topping up a failed joint typically buys very little time. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. For buildings around smaller places like Greywell, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Common questions from Greywell clients
Can you take on a job at a hospital such as Fleet Community Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is Greywell too small for you to travel to?
Not at all. Greywell is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you replace failed glazing units?
No. A glazing contractor handles that. What we seal are the joints around frames and panels.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
