Mastic sealing for commercial buildings in Spencers Wood

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. If you have a mix of products and colours from past repairs and window mastic that has split and shrunk, we can put it right, on communal kitchens and washrooms, balcony and threshold joints and window and door perimeters on blocks alike. One point of contact handles commercial sealant work in Spencers Wood from the first photos to the final walk-round, for single jobs and planned programmes alike.

Converted and older buildings in and around Spencers Wood often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Our process

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes one or more days per building, depending on the joint lengths and the access. For a job in Spencers Wood, the main thing is a clear picture of the work, so send photos of each area. You will then get a fixed price for the work.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Before we start on site

  • Flag any permit to work we will need
  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot

General trades versus a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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, which is what makes a joint last.

Why deal with it now?

Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. In a smaller place such as Spencers Wood, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Why choose Mastic Doctor in Spencers Wood

  • Work to your specification and the manufacturer’s guidance
  • Colours chosen to suit frames, cladding or finishes where possible
  • Standard and matched colours in many product ranges
  • CSCS-carded applicators

Your questions answered

Will you take on work at estates like Heron Industrial Estate, close to Spencers Wood?

Yes. We cover Spencers Wood and the area around it, including industrial estates, business parks and retail parks such as Heron Industrial Estate. Photos and a short description are enough for a first look.

We manage a building near Reading Green Park 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 work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Can weather delay the job?

It can, when the joints are outside. 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.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

Aftercare for building managers

After handover, a little attention goes a long way:

  • Look at the sunniest and most exposed elevations first
  • Include mastic in your cyclical inspections
  • Plan resealing building by building rather than complaint by complaint
  • Have the asbestos survey to hand for older buildings

Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over.

Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.

Do you need mastic sealing in Spencers Wood?

Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant and the repair soon fails.

Any of the following is a good reason to get the joints checked over:

  • Communal area joints that look neglected
  • The same joint failures repeated across a portfolio
  • Failed external movement joints
  • No planned programme for sealant

For owners of several units at places like Heron Industrial Estate, 0.6 miles to the south of Spencers Wood, one programme can deal with frame and external mastic across the lot.

Before you book anyone

  • The terms of the workmanship guarantee
  • Will CSCS-carded applicators be on site?
  • How joint depth will be controlled
  • Are they CHAS accredited or on Constructionline?

How to choose a sealant contractor

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Working within restricted access windows
  • How much existing material needs removing
  • The size and state of each joint
  • Site requirements such as inductions and permits

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • Access details, including height
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • When you need the work done

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Block-wide mastic in Spencers Wood

Spencers Wood lies roughly 38 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Spencers Wood included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

If you look after a block within reach of Reading Green Park station, 2.6 miles north-west of Spencers Wood, frame and balcony mastic can be renewed on one programme. Older community buildings, St Michael and All Angels among them, often have frames of mixed ages whose mastic varies.

Spencers Wood is about 4 miles south of Reading, in Wokingham. Anywhere in RG7, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 42 places in Wokingham.
