Mastic sealing in Tangley

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

Mastic sealing in Tangley, done properly

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. We work on communal kitchens and washrooms, external wall and movement joints and window and door perimeters on blocks, and the usual reasons a site gets in touch are failed external movement joints and brittle perimeter mastic across a building. One point of contact handles commercial sealant work in Tangley from the first photographs to the final walk-round, whether it’s one building or several.

For buildings around smaller places like Tangley, we group work so one trip covers it. Send photos of the frames and joints and we will give a fixed quote.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

From enquiry to sign-off

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a few days for most blocks, with larger programmes scheduled building by building. For a building around Tangley, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. We remove the old mastic completely and clean the joint faces back.
  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.

Frames, entrances and external joints in Tangley

Tangley lies roughly 64 miles out from central London. Managed blocks of flats are a big part of commuter-belt property. Rainfall across the South East, Tangley included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.

If you look after a block within reach of Andover station, which lies south of Tangley, frame and balcony mastic can be renewed on one programme. If you are responsible for a building such as Church of St Thomas of Canterbury, frame and door mastic needs the same attention as any other property.

Tangley is about 5 miles north-west of Andover, in Hampshire. We send applicators to Tangley for mastic joints. Tangley is one of 723 places we cover in Hampshire. For work in that direction, see our Southampton page.

We take on mastic joints across the SP11 postcode area, for business premises of every kind. Sites close to Tangley are covered too, including Chute Forest (1 mile south-west), Hatherden (2 miles south-east), Upper Chute (2 miles west), Clanville (2 miles south) and Redenham (3 miles south-west). Nearby towns on our patch include Andover (5 miles south-east), Tidworth (6 miles west), Ludgershall (4 miles west), Whitchurch (9 miles east), East Anton (4 miles south-east) and Overton (12 miles east).

Building owners, agents and FMs in Tangley

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Site staff or a sealant specialist?

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Why deal with it now?

Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. One visit to deal with every failing joint makes more sense than several trips to a place like Tangley, rather than one at a time. Send photos of each area and we will quote for the lot.

Whether it’s a single area or a whole estate, the same things set the price: 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.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Broken glass or failed sealed units
  • Asbestos-containing sealant, which we don’t remove

If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.

Joints and surfaces we work on

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

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Prioritise elevations facing the weather
  • Plan resealing building by building rather than complaint by complaint
  • Mention RAMS, insurance or CSCS requirements up front
  • Check the asbestos register before any old mastic is disturbed

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

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.

FAQs: Tangley

Is Tangley too far out for you?

No. Places such as Tangley are covered as much as the big towns. London and every South East county are within our area. 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. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.

Do you check for asbestos in old sealant?

Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.

Can you take on resealing for a block portfolio?

We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.

Can people stay in the building while you reseal?

The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.

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.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
