Mastic sealing for commercial buildings in Edgware Bury
Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. The enquiries we see most involve no planned programme for sealant and worn sealant at communal door frames, on window and door perimeters on blocks, shopfronts below residential blocks and balcony and threshold joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Edgware Bury is the same: the right product in a properly prepared joint.
Across Greater London, Edgware Bury included, the ULEZ applies, and parking and loading rules differ from street to street. For block-wide work, a place to park and store materials saves time on every visit.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Work for main contractors and building owners
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.
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Why deal with it now?
Failed perimeter mastic lets cold air in around frames and the windows typically get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Why appoint us
- One phone line for London, the South East and Scotland
- A fixed quote before work starts
- CHAS accredited
- Old sealant cut out, never sealed over

How the quote is worked out
We price every job individually. The things that drive the figure:
- Phasing around occupants
- Whether old sealant has to be cut out first
- The product specified
- The size and state of each joint
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- The asbestos register, for older buildings
- Any specification or named product
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or send details through our quote form.

Doing it in-house
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.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Questions about Edgware Bury
We manage a building near Elstree & Borehamwood station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Can you work in a care home near Edgware Bury with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Who decides which product is used?
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.
Signs you need mastic sealing in Edgware Bury
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
It’s worth sending us details if you spot any of the following:
- Damp patches beside frames
- Repeated reactive repairs to the same buildings
- Worn sealant at communal door frames
- Patchy repairs in mismatched sealant
Older community buildings, St Andrew among them, often have frames of mixed ages whose mastic varies.
What your quote should include
- How long is the guarantee, and what does it include?
- Are they CHAS accredited or on Constructionline?
- How they’ll work around occupants
- How joint depth will be controlled
How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. In Edgware Bury, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
What we need from you
- Move anything stored against the joints
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed
