Your questions answered
Is North Aston too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Must our site in North Aston stop work while the joints are done?
Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Expansion joint sealing for commercial buildings in North Aston
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. Most enquiries involve water dripping through deck or ramp joints and weathered movement joint sealant that no longer flexes, across blockwork control joints, brickwork movement joints and car park decks and ramps. Looking for mastic applicators who cover North Aston? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In and around smaller places like North Aston, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Floors, slabs and movement joints in North Aston
The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. Central London is about 61 miles from North Aston. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
In and around North Aston, the right filler or sealant for each joint depends on the traffic and the movement it takes.

What the job involves on each surface
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, normally low-modulus.
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.
Signs you need expansion joint sealing in North Aston
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.
Site and facilities staff are often the first to spot these:
- Sealant peeling off one face of the joint
- Movement joints with split or torn sealant
- Debris jammed in movement joints
- Hardened, cracked sealant on exposed facades
For an occupier at a site such as Hatch End Old Industrial Estate, which lies south of North Aston, the joints at loading doors and dock levellers usually see the hardest wear.
What your quote should include
- Proof of insurance
- Will CSCS-carded applicators be on site?
- Will failed sealant be removed rather than covered?
- Whether primer will be used where the manufacturer specifies it

From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. For a building around North Aston, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Share the asbestos register for older buildings
- Let us know about inductions and permits
- Tell staff and tenants when we will be in

Quoting for work in North Aston
A fixed quote reflects the actual work. It takes account of:
- Access and working height
- Joint width, depth and condition
- Whether the work must be split into stages
- How much existing material needs removing
A quote for movement joints depends on quantities, condition and access. Call for a quote.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Any dates the work must fit around
- How the joints are reached, and at what height
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or use the quote form to discuss it first.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
What we can’t put right
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Changing the joint layout or spacing of a structure
- Waterproofing layers buried beneath the sealant
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If in doubt, call the office on 01277 525 020 or use the quote form and we’ll say what we think before you book.
