Mastic sealing for commercial buildings in Edgcott

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. The enquiries we see most involve repeated reactive repairs to the same buildings and cracked, hardened mastic round windows on a block, on balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Edgcott it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Owners and agents with buildings around smaller places such as Edgcott tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Mastic sealing in Edgcott: the local picture

Edgcott is about 48 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Rainfall across the South East, Edgcott included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.

With historic buildings such as Claydon House (3 miles north-east of Edgcott) in the wider area, owners of older properties around Edgcott should expect mastic to need a product that suits old masonry. Property owners at sites such as Lawn Farm Business Centre, 2 miles south-east of Edgcott, can have mastic renewed between lettings. If your remit includes a building such as Grendon Underwood Combined School, frame and door mastic can be programmed for the holidays.

Edgcott is about 6 miles east of Bicester, in Buckinghamshire. Commercial clients in Edgcott use us for work on mastic joints, as part of our coverage of Buckinghamshire. We work across 308 places in Buckinghamshire. For work in that direction, see our Oxford page, about 14 miles away.

Looking after the joints

Regular inspection catches problems early. In particular:

  • Have the asbestos survey to hand for older buildings
  • Make it easy for occupiers to report draughts
  • Make mastic part of routine maintenance checks
  • Look at the sunniest and most exposed elevations first

If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.

Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.

Honest limits

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Materials that need asbestos testing before work
  • Leaks through the frame itself rather than the perimeter
  • Masonry that has broken away beside the joint

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly.

Where we work in Edgcott

  • Window and door perimeters on blocks
  • Communal kitchens and washrooms
  • External wall and movement joints

  • Balcony and threshold joints
  • Communal entrances and stairwells

Different surfaces, different methods

Planned maintenance

Resealing can be scheduled alongside other planned works on a timetable you set.

External movement joints

Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.

Your questions answered

Does your area include sites such as Lawn Farm Business Centre, near Edgcott?

Yes. We cover Edgcott and the area around it, including industrial estates, business parks and retail parks such as Lawn Farm Business Centre. A few photographs and the unit address let us price the work.

Is Edgcott too small for you to travel to?

No. Places such as Edgcott are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How much does the work cost?

Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or email the details over.

Can you take on resealing for a block portfolio?

Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Whether the work must be split into stages
  • Access and working height
  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • Your programme or deadline
  • The asbestos register, for older buildings

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or use the quote form.

From enquiry to sign-off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and we clear our waste as we work. If others near Edgcott need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
