Joints that move: notes for Owlswick

Owlswick lies roughly 37 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.

Hospitals like The Paddocks Hospital (2 miles south-east of Owlswick) have multi-storey or surface car parks whose joints carry vehicles round the clock. Schools such as Longwick Church of England Combined School have movement joints in their walls and floors that are easy to overlook.

Owlswick is about 5 miles east of Thame, in Buckinghamshire. Any commercial site in Owlswick is covered, whether it’s a single job or part of a planned programme. Owlswick is one of 308 places we cover in Buckinghamshire for movement joints. Sites around Oxford have their own page, about 16 miles away.

We take on movement joints across the HP27 postcode area, whatever the building. Just outside Owlswick, we also work in Meadle (1 mile east), Longwick (1 mile south), Ilmer (1 mile west), Alscot (1 mile south-east) and Monks Risborough (2 miles south-east).

Expansion joint sealing for commercial buildings in Owlswick

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. We work on podiums and floor movement joints, brickwork movement joints and blockwork control joints, and what we are called in for most is water getting into the wall through a failed joint and chipped joint edges on forklift routes. Looking for mastic applicators who cover Owlswick? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Smaller community and commercial buildings around Owlswick have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

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.

Why deal with it now?

Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. Halls, stores and units around places like Owlswick may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Why us?

  • Colour options checked against the specified product
  • Colours chosen to suit frames, cladding or finishes where possible
  • Over 20 years of commercial sealing
  • Products installed to the manufacturer’s instructions

See our cost guide and our accreditations and insurance.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Changing the joint layout or spacing of a structure
  • Leaks coming from the membrane rather than the joint seal

If in doubt, call the office on 01277 525 020 or email us and we will say what we think.

Where we work in Owlswick

  • Brickwork movement joints
  • Car park decks and ramps
  • Blockwork control joints
  • Precast concrete panel joints
  • Podiums and floor movement joints
  • Cladding panel joints

What sets the cost

Each job is priced on its own details. The main factors are:

  • Site requirements such as inductions and permits
  • Phasing around occupants
  • Access and working height
  • Which sealant the job calls for

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Sending details for a quote

A few photographs plus some basic facts will normally do. It helps to include:

  • Any dates the work must fit around
  • Specification clauses that apply
  • Where the site is, with the postcode
  • Clear photos of the problem areas

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

FAQs: Owlswick

Is Owlswick too small for you to travel to?

Not at all. Owlswick is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will our site in Owlswick have to close for joint sealing?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we’ll price the work to it.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Can you work while the building is occupied?

Usually, yes. We phase the work so most of the building stays in use.

Do you need expansion joint sealing in Owlswick?

Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.

It’s worth sending us details if you spot any of the following:

  • Spalled or broken joint edges in floors and decks
  • Layers of sealant in a movement joint
  • Joints packed with grit and debris
  • Water dripping through deck or ramp joints

Campuses like University Campus Aylesbury Vale, 4.9 miles north-east of Owlswick, mix old and new buildings, with movement joints wherever they meet.

Before you book anyone

  • How they’ll work around occupants
  • How they handle RAMS and site documents
  • Are they CHAS accredited or on Constructionline?
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Owlswick. Several sites can go on one quote, which keeps the paperwork simple.

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around Owlswick can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Before we start on site

  • Agree which areas must stay open
  • Explain the parking and delivery arrangements
  • Confirm the product named in the specification

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
