How we handle mastic sealing in Owslebury Bottom

Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. Most enquiries involve no planned programme for sealant and draughts at frames across a block, across external wall and movement joints, communal entrances and stairwells and balcony and threshold joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Owslebury Bottom it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Owslebury Bottom, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

From enquiry to sign-off

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 the sealant is tooled off neatly. For work around Owslebury Bottom, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Questions we are asked in Owslebury Bottom

Is Owslebury Bottom too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Do you cover business parks and estates near Owslebury Bottom, such as Hazeley Enterprise Park?

Yes. Our area takes in Owslebury Bottom and its surroundings, with estates and business parks such as Hazeley Enterprise Park included. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

What do you charge?

Each job is quoted on its own details. For yours, call the office on 01277 525 020 or email the details over with a description of the work.

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 seal joints high up on a block?

We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

Doing it in-house

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

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.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

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. We can agree access arrangements and keyholder contacts beforehand.

Why act early in Owslebury Bottom

Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. Converted and older buildings near places like Owslebury Bottom tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Why us?

  • One number for every site we cover
  • A fixed quote before work starts
  • Failed material removed, not covered up
  • A Constructionline member, so easy to vet

Quoting for work in Owslebury Bottom

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Distance, for remote addresses
  • How much existing material needs removing
  • Induction, permit and paperwork requirements
  • Joint width, depth and condition

Pricing mastic joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply
  • Clear photographs of the problem areas
  • Where the site is, with the postcode

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, call 01277 525 020 or email drawings and photos.

Maintenance after handover

To get the most from the new sealant:

  • Start inspections with the most exposed faces
  • Avoid piecemeal callouts where you can
  • Keep bins and bikes away from communal door frames
  • List the paperwork your organisation requires when you send details

Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.

Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

Frames, entrances and external joints in Owslebury Bottom

Central London is about 61 miles from Owslebury Bottom. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.

Schools and community buildings such as Owslebury Primary School need frame and external mastic kept sound like any building. Older community buildings, Church of St Andrew among them, often have frames of mixed ages whose mastic varies. Blocks of flats and mixed-use buildings often cluster around stations such as Shawford station (to the west of Owslebury Bottom) and their window and balcony mastic tends to age at the same rate across a building.
