Expansion joint sealing in Gawcott, done properly
Mastic Doctor has sealed movement joints since 2005. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. If you’re dealing with torn sealant in brick or block movement joints and sealant pulling off the joint face, we can put it right, on blockwork control joints, car park decks and ramps and cladding panel joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Gawcott, preparation and product choice get the time they need.
Jobs around smaller places like Gawcott are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Traffic, movement and joints around Gawcott
At about 51 miles from central London, Gawcott is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day. Gawcott has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
If you manage units on an estate such as Buckingham Industrial Estate (1.2 miles east of Gawcott), the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Large sites such as Buckingham Community Hospital (to the north-east of Gawcott) have car parks, service roads and long elevations with movement joints in brick and panels.
Gawcott is about 2 miles south-west of Buckingham, in Buckinghamshire. Across the MK18 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 308 places across Buckinghamshire fall within our area, Gawcott among them. There’s a separate page for Oxford, roughly 18 miles from Gawcott.

Signs you need expansion joint sealing in Gawcott
The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.
Site and facilities staff are often the first to spot these:
- Sealant peeling off one face of the joint
- New sealant over old, now failing
- Arrises breaking up along floor joints
- Expansion joints filled with dirt and stones
At places like Tingewick Road Industrial Estate, 1.3 miles north-east of Gawcott, joints are sealed a section at a time so operations carry on.
Comparing quotes
- Is the sealant right for the movement and the substrate?
- What level of public liability insurance do they hold?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether primer will be used where the manufacturer specifies it
How the job changes by surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.
What affects the price in Gawcott
Quotes vary with the job. It mainly depends on:
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
- Access and working height
- Quantities, in metres or numbers
Small jobs and large programmes are priced from the same things: 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.
Before you send an enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- Specification clauses that apply
- Rough lengths or quantities, or drawings if you have them
- Access details, including height
- The site address and postcode
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Questions about Gawcott
Can you work on a hospital site such as Buckingham Community 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.
Is Gawcott off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can a joint be sealed if the edges are broken?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.
How long does movement joint sealing take?
The metres of joint, the access and the amount of removal decide it. Typically it takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing.
Can you work on car park ramps and decks?
Yes. We use a sealant designed for wheel loads and the expected movement with bays phased so the car park keeps operating.
What causes movement joint sealant to fail?
Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting.
On site: what to expect
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Jobs in and around smaller places like Gawcott are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- Confirm the product named in the specification
- 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 you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email the details over.

What else we do in Gawcott
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
