Construction mastic for commercial buildings in North Aston
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, and we’re fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. Site teams most often ask us about failed sealant in an existing building being refurbished and cracks opening in caulked internal joints, across window and door perimeters, brick and block movement joints and sanitary and kitchen joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in North Aston, that means joint design, primers and backing rod as standard.
In the countryside around places like North Aston, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

When to call us in North Aston
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage.
Common reasons buildings call us in:
- A long mastic snag list close to completion
- Frame perimeters left unsealed or poorly sealed
- Failed sealant in an existing building being refurbished
- Different trades sealing to different standards
For contractors building in or near North Aston, we seal to the drawings, the specification and the programme.
Before you book anyone
- Whether old or failed sealant will be cut out, not overlaid
- Whether their applicators hold CSCS cards
- How long is the guarantee, and what does it include?
- How they handle RAMS and site documents
What the job involves on each surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services, and we’ll tell you if the detail calls for something else. Tell us what records you need and we will confirm with the quote.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
FAQs: North Aston
Will you take on work at estates like Hatch End Old Industrial Estate, close to North Aston?
Yes, sites like Hatch End Old Industrial Estate are within our area, along with the rest of North Aston. A few photos and the unit address let us price the work.
Can you work to our programme on a site in or near North Aston?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
How do you work with the site programme?
We seal plot by plot or floor by floor as areas are released. The sequence is settled with your site team.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
What do you charge?
Each job is quoted on its own details. For yours, call 01277 525 020 or email a schedule or drawings.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

At about 61 miles from central London, North Aston is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.
Recladding or extending a unit at a site like Hatch End Old Industrial Estate, 1.6 miles to the south of North Aston, brings panel joints and frame perimeters into the programme.

Leave it or put it right?
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go and saves applicators coming back again and again. Snagging can be priced as a separate stage. Halls, stores and units around places like North Aston may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
