About our mastic sealing in Bucks Hill

Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable throughout. We work on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints, and what we are called in for most is complaints coming in block by block and the same joint failures repeated across a portfolio. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Bucks Hill, that means joint design, primers and backing rod as standard.

For owners with a single building near Bucks Hill, we plan to finish in one visit where possible. Send photos of the frames and joints and we’ll give a fixed quote.

Work we carry out in Hertfordshire comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we’ll come back to it.

Planned mastic for Bucks Hill portfolios

The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Bucks Hill is about 21 miles from central London. 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 community buildings, Church of St Paul among them, often have frames of mixed ages whose mastic varies. For agents with blocks near Kings Langley station, 1.8 miles to the north-east of Bucks Hill, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Bucks Hill is about 4 miles north of Rickmansworth, in Hertfordshire. Businesses, contractors and managing agents in Bucks Hill can call on us for mastic joints. We work across 371 places in Hertfordshire, from busy centres to rural villages. Our London page has more on work in that area, about 21 miles away.

If you need mastic sealing in WD4, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Just outside Bucks Hill, we also work in Sarratt (1 mile south-west), Micklefield Green (1 mile south), Chandler's Cross (1 mile south-east), Hunton Bridge (2 miles east) and Loudwater (2 miles south).

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • Removal of failed or old sealant
  • Joint width, depth and condition
  • Working within restricted access windows
  • The site’s rules and procedures

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Whether the building will be occupied during the work
  • The asbestos register, for older buildings
  • When you need the work done
  • The postcode of the building

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or send photos by email if you’d rather talk the job through.

Why deal with it now?

Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Older rural buildings around Bucks Hill move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Why us?

  • Our applicators hold CSCS cards
  • Colour options checked against the specified product
  • Failed material removed, not covered up
  • Workmanship guaranteed for 12 months

Questions about Bucks Hill

Is Bucks Hill too far out for you?

No. Places such as Bucks Hill are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Can you quote for a block close to Kings Langley station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

How do you reach windows on upper floors?

It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

How many days will you need on site?

It depends on the scope, but the work typically takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Encourage occupiers to report problems at frames
  • Group repairs into a planned programme
  • Reduce knocks to communal area joints
  • Share the asbestos register when you send details

Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.

Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.

Surface by surface

Planned maintenance

We can work into your cyclical maintenance plan, building by building.

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.

When to call us in Bucks Hill

UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.

Clients normally get in touch after noticing something like this:

  • Water getting in round frames after rain
  • Worn sealant at communal door frames
  • Occupiers reporting cold air round windows
  • Patchy repairs in mismatched sealant

With historic buildings such as Chenies Manor House, 2.8 miles to the south-west of Bucks Hill, in the wider area, owners of older properties around Bucks Hill should expect mastic to need a product that suits old masonry.

Before you book anyone

  • How the joint faces will be prepared and primed
  • How they handle RAMS and site documents
  • Can the work be phased to keep areas open?
  • Health and safety accreditation such as CHAS
