Building owners, agents and FMs in Green Street
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
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, with each stage agreed with your site contact.
How we handle mastic sealing in Green Street
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you have leaks at window and door perimeters and occupiers reporting cold air round windows, we can put it right, on shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints alike. A specialist sealant contractor works differently from a general builder: in Green Street, that means joint design, primers and backing rod as standard.
Rural conversions near places like Green Street often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Do you need mastic sealing in Green Street?
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Regular cleaning wears them further.
Most enquiries start with something like this:
- Water getting in round frames after rain
- Damaged joints in communal entrances and corridors
- Repeated reactive repairs to the same buildings
- A mix of products and colours from past repairs
Landlords with units on estates such as Pebsham Rural Business Centre, 1.8 miles to the south of Green Street, can bring frame, door and external mastic across several units into one programme.

Our process
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Green Street need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.

- Explain the parking and delivery arrangements

When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Maintenance after handover
After handover, these steps help:
- Keep a record of when each building was resealed
- Reduce knocks to communal area joints
- Look at the sunniest and most exposed elevations first
- Avoid piecemeal callouts where you can
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.

Why it’s worth doing now in Green Street
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Around Green Street, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Why clients in Green Street choose us
- A Constructionline member, so easy to vet
- Clear, fixed quotes
- Colours confirmed for the specified product
- Joints cleaned back to sound surfaces
