Questions about Chalgrove

Is a smaller place like Chalgrove outside your area?

No. Places such as Chalgrove are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Must our site in Chalgrove stop work while the joints are done?

Typically not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Can you seal car park deck joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement with bays phased so the car park keeps operating.

How we handle expansion joint sealing in Chalgrove

Long runs of brick or block have movement joints built in. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. The enquiries we see most involve brittle, chalky sealant on external joints and debris jammed in movement joints, on brickwork movement joints, precast concrete panel joints and car park decks and ramps. Searching for sealant specialists in Chalgrove? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around Chalgrove, most floor and movement joint jobs are single buildings or yards, so we gather photos and measurements first. That way the right materials come on the day and the job is done in one visit where possible.

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

Looking after the joints

A few simple habits keep the new joints working:

  • Look over external and deck joints after a hard winter
  • Keep stones and debris out of open joint lines
  • Plan racking layouts so feet don’t land on a joint
  • Put movement joints on the planned maintenance inspection round

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. A sound seal keeps the joint working.

General trades versus a specialist

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, which is what makes a joint last.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Floors, slabs and movement joints in Chalgrove

The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint. Chalgrove lies roughly 44 miles out from central London. The roads out of London are lined with trade parks and distribution sheds.

Office parks like Monument Business Park (0.7 miles east of Chalgrove) have decks, ramps and clad elevations whose joints take movement every day. For a school such as Chalgrove Community Primary School, playground and building joints can be done in the holidays.

How the job changes by surface

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors, with a flexible sealant where movement is larger.

From enquiry to sign-off

The first thing on site is a walk round with your contact, 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. Work in places the size of Chalgrove is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Before we start on site

  • Warn occupants and staff about the work
  • Confirm the product named in the specification
  • Share the asbestos register for older buildings

Advice

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down. In a smaller place such as Chalgrove, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

There’s no price list, since every building and every scope is different. Call for a quote.
