Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Mastic sealing for commercial buildings in Hailey
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. If you’re dealing with draughts at frames across a block and cracked, hardened mastic round windows on a block, we can help. For commercial sealant work in Hailey, you deal with one contact from quote to sign-off, whether it’s one building or several.
For owners with a single building near Hailey, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Our workmanship is guaranteed for 12 months, in Hailey as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Why it’s worth doing now in Hailey
Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Cutting out and resealing properly does it once. Older rural buildings around Hailey move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Looking after buildings in and around Hailey
Hailey lies roughly 20 miles out from central London. Managed blocks of flats are a big part of commuter-belt property. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
For owners of several units at places like The Maltings Business Centre, which lies east of Hailey, one programme can deal with frame and external mastic across the lot. For a school such as Roselands Primary School, perimeter mastic on windows and doors is a holiday job. Buildings close to stations like St Margarets (Herts) station (1.1 miles north-east of Hailey) are often flats over shops, with frame mastic to keep sound.

For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Hailey, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

What affects the price in Hailey
Quotes vary with the job. It mainly depends on:
- Which sealant the job calls for
- Location, for remote and island sites
- Induction, permit and paperwork requirements
- Any access equipment needed
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- When you need the work done
- Whether the building will be occupied during the work
- How the joints are reached, and at what height
- Where the site is, with the postcode
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email us.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Failed window or door frames, which need a window contractor
- Broken glass or failed sealed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think.
Joints and surfaces we work on
- Communal kitchens and washrooms
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
Questions we’re asked in Hailey
Does your area include sites such as The Maltings Business Centre, near Hailey?
Yes. We cover Hailey and the area around it, including industrial estates, business parks and retail parks such as The Maltings Business Centre. A few photos and the unit address let us price the work.
Is a smaller place like Hailey outside your area?
No. Places such as Hailey are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Can you plan resealing across several buildings?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
