Mastic sealing near Upper Kingston

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

Leave it or put it right?

Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Halls, stores and units around places like Upper Kingston may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Questions we’re asked in Upper Kingston

Is Upper Kingston too far out for you?

Not at all. Upper Kingston is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Is Crow Arch Lane Industrial Estate, near Upper Kingston, within your area?

Yes. Estates, retail parks and business parks around Upper Kingston, Crow Arch Lane Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Will residents or tenants be disturbed?

Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.

How long do sealant joints last?

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

What about access for upper-floor joints?

Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Access and working height
  • Travel to remote or island sites
  • Working within restricted access windows
  • Specialist products, such as fire-rated or hygienic sealants

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • Clear photos of the problem areas
  • Approximate linear metres or a joint schedule
  • When you need the work done
  • Anything awkward about access or site hours

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, ring 01277 525 020 or email us.

Doing it in-house

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

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. For a building around Upper Kingston, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Preparing the site

  • Tell us which areas need to stay in use
  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

Advice

Mastic sealing in Upper Kingston: the local picture

Rainfall across the South East, Upper Kingston included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. The 2 miles around Upper Kingston include four care or nursing homes. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.

Trustees of buildings like Trinity Congregational Church can bring frame and external mastic into a planned maintenance list. For a school such as Ringwood Junior School, perimeter mastic on windows and doors is a holiday job. For owners of several units at places like Crow Arch Lane Industrial Estate, which lies north-west of Upper Kingston, one programme can deal with frame and external mastic across the lot.
