Mastic sealing in Tilehurst

For blocks and buildings in Tilehurst and across Reading, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. The enquiries we see most involve old repairs sealed over failed mastic and communal area joints that look neglected, across communal entrances and stairwells, balcony and threshold joints and window and door perimeters on blocks. Looking for mastic applicators who cover Tilehurst? We’ve been sealing commercial buildings since 2005.

Converted and older buildings in and around Tilehurst often put modern windows into old walls. The mastic there needs to suit both surfaces.

Surface by surface

Commercial and mixed-use buildings

Tenants in commercial buildings need to keep trading, so we plan around them.

Estate-wide resealing programmes

Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Misted or failed double-glazed units
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer.

Surfaces we seal

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

Mastic sealing in Tilehurst: the local picture

At about 41 miles from central London, Tilehurst is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Tilehurst sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

If you’re responsible for a building such as Tilehurst Methodist Church, frame and door mastic needs the same attention as any other property. Owners of student blocks near University of Reading, 3.3 miles to the east of Tilehurst, can schedule frame and external mastic for the summer vacation.

When to call us in Tilehurst

Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.

Look out for the following:

  • Water getting in round frames after rain
  • Occupiers reporting cold air round windows
  • Complaints coming in block by block
  • Patchy repairs in mismatched sealant

Buildings close to stations like Tilehurst station, 0.8 miles to the north of Tilehurst, are often flats over shops, with frame mastic to keep sound.

How to choose a sealant contractor

What happens if it’s left?

Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Small buildings around Tilehurst suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

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

Why choose Mastic Doctor in Tilehurst

  • 12-month guarantee on workmanship
  • Old sealant cut out, never sealed over
  • CSCS-carded applicators
  • CHAS accredited

Tilehurst: questions and answers

Will you take on work at estates like Oxford Road Business Park, close to Tilehurst?

Yes. We cover Tilehurst and the area around it, including industrial estates, business parks and retail parks such as Oxford Road Business Park. Send details of the unit and the work through our quote form for a quick quote.

Is a smaller place like Tilehurst outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Does the weather affect the 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. Inside work is seldom held up.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

How do you handle work on occupied blocks?

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.

Do you guarantee the mastic work?

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

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For a site in Tilehurst, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  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. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Getting the site ready

  • Point out parking and an unloading spot
  • Tell us which areas need to stay in use
  • Move anything stored against the joints

Getting a fixed quote

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or speak to us on 01277 525 020 or email a schedule or drawings to discuss it first.
