Mastic sealing for commercial buildings in Greenwich
Across Greenwich and the rest of Greater London, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote, and site visits can be arranged. The enquiries we see most involve draughts at frames across a block and failed external movement joints, on shopfronts below residential blocks, window and door perimeters on blocks and communal kitchens and washrooms. One point of contact handles commercial sealant work in Greenwich from the first photos to the final walk-round, whether it’s one building or several.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. Work is planned with the agent so residents get notice and access is arranged in advance.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What affects the price in Greenwich
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Site requirements such as inductions and permits
- Distance, for remote addresses
- Removal of failed or old sealant
- Any access equipment needed
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:
- Any dates the work must fit around
- Anything awkward about access or site hours
- Any specification or named product
- Whether the building will be occupied during the work
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or email a schedule or drawings.
Questions we’re asked in Greenwich
Can work in a care setting near Greenwich go ahead while residents are there?
Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.
We manage a building near Maze Hill station. Can you help?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do you work in Greenwich?
Yes. Greenwich is in our area, within our coverage of Greater London, South East England and Scotland. To discuss a job, phone 01277 525 020 or email the details over.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long does a job like this take?
That varies with the scale of the job, but the work typically takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
On site: what to expect
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. In Greenwich, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Preparing the site
- Let building users know which areas are affected
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000

Work for main contractors and building owners
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
After the work
A few simple habits keep the new joints working:
- Reduce knocks to communal area joints
- Check sealant joints during planned building inspections
- Start inspections with the most exposed faces
- Group repairs into a planned programme
Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
Surface by surface
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Planned mastic for Greenwich portfolios
Blocks in London are normally run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We plan around the notices and access you arrange. Four care or nursing homes sit less than 2 miles from Greenwich. Care home owners need frame and external mastic kept sound without unsettling residents.
Buildings close to stations like Maze Hill station, under half a mile north-east of Greenwich, are often flats over shops, with frame mastic to keep sound. If you are responsible for a building such as St Mary's Church, frame and door mastic needs the same attention as any other property. If you manage student housing near a university such as University of Greenwich (less than half a mile north-west of Greenwich), the summer turnaround is the time for mastic.
