Honest limits
Some faults sit outside our scope, and we say so rather than covering them up:
- Substrate edges that need repairing first
- Leaks from above rather than through a joint
- Materials that need asbestos testing before work

Mastic sealing for commercial buildings in Broadgate
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in Broadgate carry our 12-month guarantee. We work on external wall and movement joints, shopfronts below residential blocks and balcony and threshold joints, and what we’re called in for most is window mastic that has split and shrunk and the same joint failures repeated across a portfolio. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Broadgate, that means joint design, primers and backing rod as standard.
For owners with a single building near Broadgate, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Block-wide mastic in Broadgate
Rainfall across the South East, Broadgate included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first. Central London is about 66 miles from Broadgate. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate.
Buildings close to stations like Chandlers Ford station (to the south-east of Broadgate) are often flats over shops, with frame mastic to keep sound. If you’re responsible for a building such as Church of St Mark, frame and door mastic needs the same attention as any other property. If you own or manage units on a site such as Sleepy Hollow Business Park, 1.2 miles to the west of Broadgate, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Questions we are asked in Broadgate
Do you cover business parks and estates near Broadgate, such as Sleepy Hollow Business Park?
Yes, sites like Sleepy Hollow Business Park are within our area, along with the rest of Broadgate. A few photos and the unit address let us price the work.
Will you take on a block within reach of Chandlers Ford station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Do you cover Broadgate?
Yes. Sites across Broadgate are covered, with one number for every area we cover.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you do block-wide mastic programmes?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
Why deal with it now?
Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure and less choice about when. For buildings around smaller places like Broadgate, 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.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
