Mastic sealing near Poets Estate

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

Mastic sealing for commercial buildings in Poets Estate

We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. If you’re dealing with damaged joints in communal entrances and corridors and water getting in round frames after rain, we can help. One point of contact handles commercial sealant work in Poets Estate from the first photographs to the final walk-round, whether it’s one building or several.

Older buildings and conversions around places like Poets Estate mix old masonry with newer frames. The mastic there needs to suit both surfaces.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. If neighbouring businesses or buildings around Poets Estate need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  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. Buildings are completed in turn.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Send your site hours and access windows
  • Arrange parking or a loading space

Quotes

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Advice

Frames, entrances and external joints in Poets Estate

Poets Estate is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building typically need attention first. Three care or nursing homes sit less than 2 miles from Poets Estate. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.

If you are responsible for a building such as St Faith's Church, frame and door mastic needs the same attention as any other property. If your remit includes a building such as William Ransom Primary School, frame and door mastic can be programmed for the holidays.

Poets Estate is about 1 mile east of Hitchin, in Hertfordshire. We send applicators to Poets Estate for mastic joints. We work across 371 places in Hertfordshire, large and small. For work in that direction, see our London page, about 32 miles away.

Owners, agents and contractors

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Substrate edges that need repairing first
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Frames that are rotten, warped or broken

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Where we work in Poets Estate

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

Poets Estate: questions and answers

Will you take on a block within reach of Hitchin station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.

Is Poets Estate off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

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.

What if the old mastic contains asbestos?

We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.

Can you seal joints high up on a block?

We talk through access for each building when we quote. Tell us the building height and any access already in place, and we will tell you how we’d approach it.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Can you plan resealing across several buildings?

Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.

Common problems we fix in Poets Estate

Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.

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

  • Communal area joints that look neglected
  • Damp patches beside frames
  • Failed external movement joints
  • The same joint failures repeated across a portfolio

For owners of several units at places like Letchworth Gateway Retail Park, 2.8 miles north-east of Poets Estate, one programme can deal with frame and external mastic across the lot.

Questions to ask before you book

  • Which product they’ll use, and why it suits the joint
  • Can the work be phased to keep areas open?
  • Will failed sealant be removed rather than covered?
  • Who will actually carry out the work

Choosing a commercial sealant contractor

What affects the price in Poets Estate

Each job is priced on its own details. The things that drive the figure:

  • Joint width, depth and condition
  • How much there is to seal
  • Working within restricted access windows
  • Site requirements such as inductions and permits

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Clear photos of the problem areas
  • Anything awkward about access or site hours
  • The asbestos register, for older buildings
  • The site address and postcode

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or send photos by email if you’d rather talk the job through.

Different surfaces, different methods

Commercial and mixed-use buildings

Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.

External movement joints

The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.
