Traffic, movement and joints around Lower Assendon
Lower Assendon is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. Lower Assendon is about 36 miles from central London. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.
University campuses such as University of Reading, 4.5 miles to the south of Lower Assendon, have car parks, paved walkways and building elevations with movement joints. Hospitals like Townlands Memorial Hospital (to the south-east of Lower Assendon) have multi-storey or surface car parks whose joints carry vehicles round the clock. For a school such as Rupert House School, playground and building joints can be done in the holidays.
Lower Assendon is about 6 miles north of Caversham, in Oxfordshire. We cover Lower Assendon and the rest of Oxfordshire, with the same fixed quotes and 12-month guarantee as everywhere else.

Our process
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Lower Assendon need work, visits can be combined. You’ll have a fixed quote before work starts.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- You get a fixed quote with the product and the phasing set out.
- We remove failed material and packed debris until sound concrete is exposed on both faces.
- We vacuum each run and prime it if the chosen product requires a primer.
- The chosen product is placed to its specified depth and trimmed level with the floor.
- Each phase reopens when the product is ready for wheels, then we start the next.
What we need from you
- Have the specification and drawings to hand
- Make sure the joints can be reached
- Explain the parking and delivery arrangements
Getting a fixed quote
For a fixed quote, phone 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.
Advice
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Expect fillers on young slabs to need a top-up
- Hold traffic back until the product has cured
- Let us know what the floor is cleaned with
- Put loading bays at the top of the list
A routine walk of the busiest aisles shows how the joints are holding up. Look for separation down one side, new chips in the arris and debris gathering, and photograph anything that changes.
A broken joint on a main route is crossed by every truck on that route. Sorting it early looks after your equipment as well as the slab.
What affects the price in Lower Assendon
The price varies from site to site. Expect it to depend on:
- Travel to remote or island sites
- Access and working height
- Whether the work must be split into stages
- Removal of failed or old sealant
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- Asbestos survey details if the building is older
- How the joints are reached, and at what height
- Any specification or named product
- Approximate linear metres or a joint schedule
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or send photos by email with what you know.
What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Unstable slabs moving under traffic
- Level or flatness problems across the floor
- Spalled arrises, which need an edge repair first
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly.
Surfaces we seal

General trades versus a 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.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Questions about Lower Assendon
Is Lower Assendon too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Would you work within a site like Townlands Memorial Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you repair broken joint edges?
We check the edges as part of the survey. Damaged edges are flagged up front, so nothing is filled that won’t hold.
Why has the filler pulled away from one side?
Young concrete carries on shrinking for a long time and a stiff filler can separate down one side. It is normally dealt with by topping up.
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.
