Mastic sealing for Little Woodcote sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Different surfaces, different methods

Window and door perimeters on blocks

We normally work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.

How we handle mastic sealing in Little Woodcote

Managing agents and housing associations normally need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on communal entrances and stairwells, external wall and movement joints and communal kitchens and washrooms, and what we’re called in for most is leaks at window and door perimeters and mastic failing across several blocks on an estate. Whoever orders the work in Little Woodcote, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For managing agents in Little Woodcote, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What sets the cost

These are the things that shape the price:

  • Quantities, in metres or numbers
  • Phasing around occupants
  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • Whether an asbestos survey exists
  • The product your specification calls for
  • When you need the work done
  • Anything awkward about access or site hours

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, call the office on 01277 525 020 or use the quote form.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Getting the site ready

  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected

Request a quote

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 01277 525 020 or send details through our quote form.

Related advice

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

After the work

Once the work is signed off, these steps help:

  • Check the asbestos register before any old mastic is disturbed
  • Make it easy for occupiers to report draughts
  • Look at the sunniest and most exposed elevations first
  • Mention RAMS, insurance or CSCS requirements up front

Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.

Planned mastic for Little Woodcote portfolios

Seven care or nursing homes sit less than 2 miles from Little Woodcote. Owners of care premises can bring window and door mastic into a phased programme planned around the home.

For a school such as Woodmansterne Primary School, perimeter mastic on windows and doors is a holiday job. Student blocks close to universities like University for the Creative Arts - Epsom, 4.6 miles west of Little Woodcote, are easiest to work on between tenancies.

What we’re called out for in Little Woodcote

Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.

These are often picked up first by site or facilities staff:

  • Water getting in round frames after rain
  • Patchy repairs in mismatched sealant
  • Window mastic that has split and shrunk
  • Occupiers reporting cold air round windows

Blocks of flats and mixed-use buildings often cluster around stations such as Woodmansterne station (to the south of Little Woodcote) and their window and balcony mastic tends to age at the same rate across a building.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • What the guarantee covers, and for how long
  • Their plan for phasing and protecting the area
  • Is the sealant right for the movement and the substrate?

FAQs: Little Woodcote

Does your area include sites such as Ullswater Industrial Estate, near Little Woodcote?

Yes. Estates, retail parks and business parks around Little Woodcote, Ullswater Industrial Estate among them, are all within reach. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Do you take on jobs in Little Woodcote where loading and access are tightly controlled?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough

How many days will you need on site?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Can you take on resealing for a block portfolio?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee and we hold public liability insurance.
