Mastic sealing for businesses in Red Post Bridge

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Mastic sealing in Red Post Bridge, done properly

Across Red Post Bridge and the rest of Hampshire, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. Site teams most often ask us about damp patches beside frames and failed external movement joints, on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints. Most enquiries from Red Post Bridge start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Red Post Bridge, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. For a building around Red Post Bridge, 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. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Why deal with it now?

Draughts round window perimeters cost occupiers comfort and the windows usually get the blame. In many cases, new perimeter sealant deals with it when the frames themselves are sound. For buildings around smaller places like Red Post Bridge, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Mastic sealing in Red Post Bridge: the local picture

Red Post Bridge has two care or nursing homes no more than 2 miles away. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. Red Post Bridge lies roughly 65 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.

Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Landlords with units on estates such as Plot 5 Andover Business Park, under half a mile to the north-east of Red Post Bridge, can bring frame, door and external mastic across several units into one programme. For agents with blocks near Andover station, 1.9 miles east of Red Post Bridge, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Different surfaces, different methods

Communal areas

Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.

Commercial and mixed-use buildings

Where retail and residential share a building the programme has to suit everyone. We plan around the site hours and access windows you give us.

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Frames that are rotten, warped or broken
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)

If you are not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Questions about Red Post Bridge

Do you cover business parks and estates near Red Post Bridge, such as Plot 5 Andover Business Park?

Yes. Our area takes in Red Post Bridge and its surroundings, with estates and business parks such as Plot 5 Andover Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Can you work in a care home near Red Post Bridge with residents in?

Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

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. Indoors, the weather is rarely a problem.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

How long will the new sealant last?

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