Mastic sealing in Red Rice, done properly

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios.

For owners with a single building near Red Rice, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What we are called out for in Red Rice

Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.

It’s worth sending us details if you spot any of the following:

  • Failed external movement joints
  • Cracked, hardened mastic round windows on a block
  • Communal area joints that look neglected
  • Mastic failing across several blocks on an estate

If you own or manage units on a site such as Glenmore Business Park, 2.1 miles to the north of Red Rice, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Before you book anyone

  • How the joint faces will be prepared and primed
  • The terms of the workmanship guarantee
  • How they handle RAMS and site documents
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Choosing a commercial sealant contractor

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a building around Red Rice, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Preparing the site

  • Let us know about inductions and permits
  • Move anything stored against the joints
  • Tell staff and tenants when we’ll be in

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Looking after buildings in and around Red Rice

At about 65 miles from central London, Red Rice is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Red Rice sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

Buildings close to stations like Andover station, 2.6 miles to the north-east of Red Rice, are often flats over shops, with frame mastic to keep sound. Churches, halls and community buildings such as Church of St Mary the Virgin are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Red Rice is about 3 miles south-west of Andover, in Hampshire. Any commercial site in Red Rice is covered, for single jobs and planned programmes alike. Our Hampshire coverage takes in 723 places, large and small. Our Southampton page has more on work in that area, about 19 miles away.

Business premises anywhere in SP11 are within our area for mastic joints. Buildings on Red Rice Road and Fullerton Road are within our area for mastic joints. If your building is just outside Red Rice, we cover Little Ann (1 mile north), Abbotts Ann (1 mile north-west), Anna Valley (1 mile north), Monxton (2 miles north-west) and Kentsboro (2 miles south-west). Nearby towns on our patch include Winchester (12 miles south-east), Andover (3 miles north-east), Chandler's Ford (14 miles south-east), Romsey (13 miles south), Hyde (12 miles south-east) and Tidworth (8 miles north-west).

Local landmarks in Red Rice

Locally, jobs take us to sites close to Abbotts Ann Church of England Primary School and John Hanson Community School, among other places. For rail, the closest station is Andover station, roughly 2.6 miles north-east. Well-known places in the area include Andover Museum (2.8 miles north-east) and Andover War Memorial Hospital (2.8 miles north). Not far away are Mill Lake and Quarley Hill.

Honest limits

Honesty saves time and money. New sealant won’t cure:

  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Masonry that has broken away beside the joint

If in doubt, ring 01277 525 020 or send photos by email and we will say what we think before you book.

What we seal

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

Your questions answered

Is a smaller place like Red Rice outside your area?

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

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

Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.

Do you check for asbestos in old sealant?

Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Is mastic sealing guaranteed?

There is a 12-month guarantee on our workmanship, backed by public liability insurance.

Will residents or tenants be disturbed?

Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.

What about access for upper-floor joints?

Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Start inspections with the most exposed faces
  • List the paperwork your organisation requires when you send details
  • Make mastic part of routine maintenance checks
  • Log resealing dates block by block

Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.

Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

Why deal with it now?

Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Older rural buildings around Red Rice move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Why us?

  • CHAS accredited
  • 12-month guarantee on workmanship
  • Colour options checked against the specified product
  • Joints cleaned back to sound surfaces
