About our mastic sealing in Cross Lane

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. We work on communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints, and the usual reasons a site gets in touch are occupiers reporting cold air round windows and patchy repairs in mismatched sealant. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Cross Lane it comes down to the same thing: the right product in a properly prepared joint.

For landlords and associations with stock in and around Cross Lane, grouping buildings into one visit saves travel. Send the addresses and photographs and we will quote for all of them together.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Looking after the joints

Once the work is signed off, these steps help:

  • Track which buildings were done and when
  • Make it easy for occupiers to report draughts
  • Plan resealing building by building rather than complaint by complaint
  • Make mastic part of routine maintenance checks

Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.

The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.

Leave it or put it right?

Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee. For buildings in places like Cross Lane, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

A quote for mastic joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Frames that are rotten, warped or broken

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

What we seal

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

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Questions about Cross Lane

Is Cross Lane too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Will you take on work at estates like Wakes Retail Park, close to Cross Lane?

Yes. Estates, retail parks and business parks around Cross Lane, Wakes Retail Park among them, are all within reach. Photos and a short description are enough for a first look.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote.

Can you plan resealing across several buildings?

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

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.

How many days will you need on site?

It depends on the scope, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around Cross Lane need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Getting the site ready

  • Let building users know which areas are affected
  • Send your site hours and access windows
  • Move anything stored against the joints

Getting a fixed quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email a schedule or drawings.

Advice

Looking after buildings in and around Cross Lane

The 2 miles around Cross Lane include four care or nursing homes. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. Cross Lane sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.

Historic properties like Carisbrooke Castle (1.7 miles south-west of Cross Lane) show the age of some local stock, where frame mastic must suit soft brick or stone. Property owners at sites such as Wakes Retail Park, under half a mile to the west of Cross Lane, can have mastic renewed between lettings. If your remit includes a building such as Summerfields Primary School, frame and door mastic can be programmed for the holidays.

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Joint width, depth and condition
  • How much existing material needs removing
  • Access and working height
  • Which sealant the job calls for

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 you’ll have a fixed figure to work with.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • Whether the building will be occupied during the work
  • Access details, including height
  • The postcode of the building
  • The product your specification calls for

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