Common questions from Upton Grey clients

Is a smaller place like Upton Grey outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

We manage a building near Hook station. Can you help?

Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Do you work for managing agents and housing associations?

Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Can people stay in the building while you reseal?

We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.

Does weather matter for sealant work?

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.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

How we handle mastic sealing in Upton Grey

For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. The enquiries we see most involve occupiers reporting cold air round windows and no planned programme for sealant, on shopfronts below residential blocks, balcony and threshold joints and window and door perimeters on blocks. Most enquiries from Upton Grey start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Owners and agents with buildings around smaller places such as Upton Grey 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.

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.

Different surfaces, different methods

Window and door perimeters on blocks

Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.

Communal areas

Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Fresh joints make shared areas look looked after.

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

  • Broken glass or failed sealed units
  • Asbestos-containing sealant, which we don’t remove
  • Frames that are rotten, warped or broken

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Where we work in Upton Grey

  • Shopfronts below residential blocks
  • Communal kitchens and washrooms
  • Communal entrances and stairwells
  • Balcony and threshold joints
  • External wall and movement joints
  • Window and door perimeters on blocks

Cost factors for mastic joints

We price every job individually. The main factors are:

  • The size and state of each joint
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • Which sealant the job calls for

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Details that help us quote

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

  • The type of building and who uses it
  • Where the site is, with the postcode
  • How the joints are reached, and at what height
  • A wide shot and a close-up of the area

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call 01277 525 020 or send photos by email.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Upton Grey are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Getting the site ready

  • Arrange parking or a loading space
  • Make sure the joints can be reached
  • Let us know about inductions and permits

Quotes

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or send photos by email.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Mastic sealing around Upton Grey: what changes locally

Rainfall across the South East, Upton Grey included, is lower than in many 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. Central London is about 44 miles from Upton Grey. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.

Trustees of buildings like Church of St Mary can bring frame and external mastic into a planned maintenance list. Landlords with units on estates such as Hatch Industrial Park, 2.7 miles north-west of Upton Grey, can bring frame, door and external mastic across several units into one programme. Buildings close to stations like Hook station (4 miles north-east of Upton Grey) are often flats over shops, with frame mastic to keep sound.

Upton Grey is about 5 miles south-east of Basingstoke, in Hampshire.

Why act early in Upton Grey

Draughts round window perimeters cost occupiers comfort, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. One visit to deal with every failing joint makes more sense than several trips to a place like Upton Grey, rather than one at a time. Photos of every joint help us quote for the whole job.

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.

Why clients in Upton Grey choose us

  • Work carried out by CSCS-carded applicators
  • 12 months’ guarantee on every job
  • Joints cleaned back to sound surfaces
  • Coloured sealants to suit the setting, where available
