Questions we are asked in Downham
Do we have to stop operations in Downham while the joints are sealed?
Usually not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we’ll plan from there.
Can you take on a job at a hospital such as Mayflower Community Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Do you use silicone or polyurethane in movement joints?
Whatever suits the joint and the specification. The quote states the sealant and its movement class.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Do you cover Downham?
Yes. We take on work across Downham, and the same phone number covers every area.
About our expansion joint sealing in Downham
Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. We work on cladding panel joints, precast concrete panel joints and podiums and floor movement joints, and the usual reasons a site gets in touch are joints where the bead has lost adhesion and leaks through car park deck joints onto the level below. A specialist sealant contractor works differently from a general builder: on jobs in Downham, preparation and product choice get the time they need.
Halls, schools and small commercial buildings near places like Downham have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

For managing agents and facilities managers
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
What sets the cost
The price varies from site to site. Expect it to depend on:
- How much there is to seal
- Location, for remote and island sites
- Induction, permit and paperwork requirements
- Which sealant the job calls for
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
What to include in your enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- The type of building and who uses it
- When you need the work done
- The product your specification calls for
- The site address and postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
From enquiry to sign-off
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 Downham need work, visits can be combined. You will have a fixed quote before work starts.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work
- Flag any permit to work we will need
Get a fixed quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.
Advice
What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Movement on a scale no sealant is meant to absorb
- Concrete or masonry repairs along the arrises
- Changing the joint layout or spacing of a structure
If you are not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer before you book.
What we seal
- Podiums and floor movement joints
- Car park decks and ramps
- Precast concrete panel joints
- Blockwork control joints
- Brickwork movement joints
- Cladding panel joints
Different surfaces, different methods
Cladding panel joints
We confirm what access is in place before pricing. Photos taken near the joints help us price accurately.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces.
Expansion joint sealing around Downham: how the place shapes the job
The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint. Central London is about 27 miles from Downham. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day.
Schools like The Bromfords School and Sixth Form College often have long brick elevations with movement joints that age quietly. Large sites such as Mayflower Community Hospital (3.9 miles west of Downham) have car parks, service roads and long elevations with movement joints in brick and panels.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Keep racking legs and heavy point loads off floor joints
- Keep product details with the building records for the next reseal
- Check joints after long freezing spells
- Leave barriers in place until fresh joint sealant has cured
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file, so the next reseal starts with the facts.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors. Resealing promptly prevents internal damage.
