Mastic sealing in Micklefield Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Different surfaces, different methods

Tenement and older buildings

Older mastic can contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.

Communal areas

Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.

Mastic sealing in Micklefield Green

Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Entrances and stairwells are kept in use throughout. We work on shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells, and what we are called in for most is worn sealant at communal door frames and damp patches beside frames. A specialist sealant contractor works differently from a general builder: in Micklefield Green, that means joint design, primers and backing rod as standard.

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

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Frames, entrances and external joints in Micklefield Green

There are two care or nursing homes within about 2 miles of Micklefield Green. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. At about 21 miles from central London, Micklefield Green is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.

Older buildings near Micklefield Green, from historic houses such as Chenies Manor House, 2 miles west of Micklefield Green, to more modest stock, need compatible products when frames are resealed. Blocks of flats and mixed-use buildings often cluster around stations such as Chorleywood station (2 miles south-west of Micklefield Green) and their window and balcony mastic tends to age at the same rate across a building.

Advice

Owners, agents and contractors

Why it’s worth doing now in Micklefield Green

Reacting to every complaint means sending someone out block by block. A planned programme treats each building once, under a single quote and a single programme. Converted and older buildings near places like Micklefield Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Pricing mastic joints depends on quantities, condition and access. Ask us for a fixed quote.

Common problems we fix in Micklefield Green

Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.

Look out for the following:

  • Movement joints with sealant missing
  • A mix of products and colours from past repairs
  • Water getting in round frames after rain
  • Worn sealant at communal door frames

If your remit includes a building such as Sarratt Church of England Primary School, frame and door mastic can be programmed for the holidays.

How to choose a sealant contractor

Questions we’re asked in Micklefield Green

Can work in a care setting near Micklefield Green go ahead while residents are there?

Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.

Is Micklefield Green too far out for you?

No. Places such as Micklefield Green 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.

Can you reseal a whole block or estate?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

How do I request a quote?

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

What will the job cost?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

How long does a typical visit take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Do you guarantee the mastic work?

A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.

When to bring in a specialist

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

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.
