FAQs: Mid Lavant

Is a smaller place like Mid Lavant outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Do you take on work at healthcare sites like Nuffield Health Chichester Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

How do you work with the site programme?

Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready.

How much does the work cost?

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

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Construction mastic for commercial buildings in Mid Lavant

External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal sealing often fills those days. We work on brick and block movement joints, window and door perimeters and cladding and panel joints, and what we’re called in for most is frame gaps too wide for sealant alone and window and door perimeters that won’t pass inspection. Most enquiries from Mid Lavant start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Construction in and around smaller places such as Mid Lavant is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email drawings and photos and we’ll come back to it.

Sites and facades in and around Mid Lavant

Rainfall across the South East, Mid Lavant included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Central London is about 53 miles from Mid Lavant. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

University estates such as University of Chichester (2 miles south of Mid Lavant) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. New wings at hospitals like Nuffield Health Chichester Hospital, 1.7 miles south of Mid Lavant, bring long runs of window and panel joints to seal.

Commercial clients in Mid Lavant

Building owners and managing agents use us on everything from one building to a spread of sites around Mid Lavant. Several sites can go on one quote, which keeps the paperwork simple.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • The total length or number of joints
  • Whether the work must be split into stages
  • Access and working height
  • How much existing material needs removing

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.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • When you need the work done
  • Where the site is, with the postcode
  • Approximate linear metres or a joint schedule
  • The type of building and who uses it

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself typically taking a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. For work around Mid Lavant, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. You receive a fixed quote listing scope, products and phasing.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Preparing the site

Common problems we fix in Mid Lavant

A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.

Common reasons buildings call us in:

  • New external sealant already peeling away
  • Old sealant on a refurbishment that needs stripping before new work
  • Frame gaps too wide for sealant alone
  • Sanitary sealant damaged by following trades

Hotels like Hunters Lodge Hotel, under half a mile to the west of Mid Lavant, rarely close for long, so refurbishment mastic is phased floor by floor.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • What site paperwork they can supply
  • Will failed sealant be removed rather than covered?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

Why deal with it now?

A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. Sealant can’t grip a contaminated or existing bead. We cut out and redo the joint properly. One visit to deal with every failing joint makes more sense than several trips to a place like Mid Lavant, rather than one at a time. Send photographs of each area and we will quote for the lot.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why clients in Mid Lavant choose us

  • CHAS accredited contractor
  • A fixed quote before work starts
  • 12-month guarantee on workmanship
  • Colour agreed before work starts

When it isn’t the sealant

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Deciding which fire-stopping product a penetration needs
  • Frames fitted out of tolerance
  • Rework caused by others damaging completed areas

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly before you book.
