For owners and agents in Buckland

Rainfall across the South East, Buckland included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 34 miles from Buckland. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.

Site managers at schools like Freman College can fit frame mastic into the summer works. For agents with blocks near Royston station, 4.7 miles north of Buckland, a block-wide mastic programme deals with frames, balconies and entrances in one go.

How we handle mastic sealing in Buckland

On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. We work on shopfronts below residential blocks, balcony and threshold joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are open joints in brickwork or panels and draught complaints from residents or tenants. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Buckland it comes down to the same thing: the right product in a properly prepared joint.

Rural conversions near places like Buckland often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How the job changes by surface

Window and door perimeters on blocks

Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. We will confirm the colours available for the specified product.

Tenement and older buildings

Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Masonry that has broken away beside the joint
  • Broken glass or failed sealed units
  • Asbestos-containing sealant, which we don’t remove

If in doubt, ring 01277 525 020 or email us and we’ll say what we think before you book.

Surfaces we seal

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

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Buckland need work, visits can be combined. A fixed quote is given before anything starts.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Getting the site ready

  • Agree which areas must stay open
  • Share the asbestos register for older buildings
  • Send your site hours and access windows

Advice

Cost factors for mastic joints

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Any access equipment needed
  • Site requirements such as inductions and permits
  • How much existing material needs removing
  • Backing rod, priming and other preparation

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Any specification or named product
  • Where the site is, with the postcode
  • Whether an asbestos survey exists
  • When you need the work done

FAQs: Buckland

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

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

Will you take on work at estates like Park Farm Industrial Estate, close to Buckland?

Yes. Estates, retail parks and business parks around Buckland, Park Farm Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Will you just go over the old sealant?

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.

Can you reseal a whole block or estate?

Block-wide and estate programmes are common. The quote can be split however suits your budgeting.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so it can be arranged.

When to call us in Buckland

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Clients normally get in touch after noticing one or more of the following:

  • Estate-wide sealant that is simply worn out
  • Patchy repairs in mismatched sealant
  • Water getting in round frames after rain
  • Occupiers reporting cold air round windows

Landlords with units on estates such as Park Farm Industrial Estate, 2.3 miles to the south of Buckland, can bring frame, door and external mastic across several units into one programme.

What your quote should include

  • Whether primer will be used where the manufacturer specifies it
  • How long is the guarantee, and what does it include?
  • What site paperwork they can supply
  • The named product and why it was chosen
