Facade sealing in Middle Park, done properly
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. Site teams most often ask us about hard, chalky sealant that no longer flexes and draughts around frames and panels, on shopfront frames, coping and flashing joints and cladding panel joints. One point of contact handles commercial sealant work in Middle Park from the first photos to the final walk-round, for single jobs and planned programmes alike.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, call 01277 525 020 or use the quote form and we will arrange a return visit.

Why act early in Middle Park
Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Getting the site ready
- Share your working hours and any access restrictions
- Point out parking and an unloading spot
- Tell us what induction or permit system the site runs
Getting a fixed quote
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or email the details over.
Advice
Cost factors for facade joints
The price varies from site to site. Expect it to depend on:
- Induction, permit and paperwork requirements
- Which sealant the job calls for
- Whether the work must be split into stages
- Backing rod, priming and other preparation
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- Anything awkward about access or site hours
- Your programme or deadline
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Commercial clients in Middle Park
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Questions we’re asked in Middle Park
Is Green Lane Business Park, near Middle Park, within your area?
Yes. We cover Middle Park and the area around it, including industrial estates, business parks and retail parks such as Green Lane Business Park. A few photos and the unit address let us price the work.
Will you plan work around the academic year at somewhere like University of Greenwich - Avery Hill?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Is Middle Park in your area?
Yes. Sites across Middle Park are covered, and the same phone number covers every area.
Do you install glazing systems?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
How many days will you need on site?
That varies with the scale of the job, though a typical visit typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Maintenance after handover
A few simple habits keep the new joints working:
- Investigate damp beside windows promptly
- Clear debris that holds water against joints
- Confirm the survey covers external sealants in older buildings
- Add perimeter sealant to planned maintenance checks
Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards using a matching sealant.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail instead of after the damage.
Facade sealing around Middle Park: how the place shapes the job
Several hotels sit less than 2 miles from Middle Park. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. Site traffic in Middle Park falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
On a healthcare site such as Eltham Community Hospital, which lies north-east of Middle Park, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Further education sites such as Hadlow College, 0.5 miles to the south-west of Middle Park, are extended and refurbished from time to time, with mastic often programmed into the summer break. Recladding or extending a unit at a site like Green Lane Business Park, 1.1 miles to the south-east of Middle Park, brings panel joints and frame perimeters into the programme.
