Mastic sealing for businesses in Hermiston
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How we handle mastic sealing in Hermiston
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on balcony and threshold joints, window and door perimeters on blocks and communal entrances and stairwells, and the usual reasons a site gets in touch are estate-wide sealant that is simply worn out and open joints in brickwork or panels. Most enquiries from Hermiston start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
For buildings around Hermiston, we group the work to keep travel and visits down. A list of addresses and photographs lets us quote for them together.
A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Questions about Hermiston
Does your area include sites such as Hermiston Gait Retail Park, near Hermiston?
Yes. Estates, retail parks and business parks around Hermiston, Hermiston Gait Retail Park among them, are all within reach. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.
We manage a building near Edinburgh Park station. Can you help?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
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.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
Can you take on resealing for a block portfolio?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Our process
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Travel to smaller Scottish places like Hermiston is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Before we start on site
- Let building users know which areas are affected
- Send any specification or drawings in advance
- Tell us what induction or permit system the site runs

Site staff or a sealant specialist?
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.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Common problems we fix in Hermiston
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.
Any of the following is a good reason to get the joints checked over:
- Repeated reactive repairs to the same buildings
- Open joints in brickwork or panels
- Mastic failing across several blocks on an estate
- Old repairs sealed over failed mastic
Student blocks close to universities like Heriot-Watt University (to the south of Hermiston) are easiest to work on between tenancies.

Owners, agents and contractors

Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Log resealing dates block by block
- Encourage occupiers to report problems at frames
- Group repairs into a planned programme
- Make mastic part of routine maintenance checks
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
Different surfaces, different methods
Communal areas
Communal areas stay in use while we work. We work in sections so access is never blocked.
Window and door perimeters on blocks
