Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Your questions answered

Can you work at a site such as Seacourt Retail Park, by Wytham?

Yes. Estates, retail parks and business parks around Wytham, Seacourt Retail Park among them, are all within reach. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Is Wytham too small for you to travel to?

No. Small places get the same service as large ones. 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.

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.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

Do you work for facilities managers and managing agents?

Yes. Use our quote form to send the site details, or phone or email us.

Can you handle sealant work across several sites?

Yes, across South East England, Greater London and all of Scotland. Each site gets the same process and a single contact.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Commercial mastic work in Wytham

Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Wytham, ring 01277 525 020 or send photos by email with the site addresses. We work on window and door perimeters, kitchen worktops and splashbacks and floor and threshold joints, and the failures we are asked to look at most are external beads that have gone brittle and cracked and greasy, split joints in a kitchen or tea point. One point of contact handles commercial sealant work in Wytham from the first photographs to the final walk-round, whether it’s one building or several.

A lot of what we do in Wytham is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

In and around smaller places such as Wytham, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Wytham can sit alongside others in a wider programme across Oxfordshire.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Smaller jobs around Wytham can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, or we arrange a site visit.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Before we start on site

  • Agree which areas must stay open
  • Move anything stored against the joints
  • Tell staff and tenants when we will be in

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or email drawings and photos.

Why act early in Wytham

A cheaper quote sometimes means the old bead stays in. Sealing over looks tidy at handover, then lifts once the joint starts moving. Every quote we give includes full removal and preparation. Halls, stores and units around places like Wytham may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

A quote for sealant joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Why choose Mastic Doctor in Wytham

When to call us in Wytham

External sealant takes a steady beating from the weather. Sunny elevations dry the surface out and exposed ones take driving rain; in time the surface chalks, hardens and cracks. A hardened bead can’t follow the building any more.

What tends to prompt an enquiry:

  • Leaks that seem to come through a sealant line
  • Layers of sealant, all of them failing
  • Frame sealant that has cracked, shrunk or pulled away
  • Weathered facade sealant that no longer flexes

A hotel such as Leonardo Royal Hotel Oxford, 1.4 miles north-east of Wytham, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?
  • Their approach to joint depth and backing
  • How the joint faces will be prepared and primed

Our contractor checklist

Sealant on show in Wytham’s commercial buildings

The South East is one of the drier parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Wytham has two care or nursing homes no more than 2 miles away. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean; colours can be chosen to suit the interior.

Shop fits at places like Seacourt Retail Park (to the south-east of Wytham) leave counters, frontages and floor edges where the sealant colour is part of the finish. For premises near Oxford Parkway station, which lies north-east of Wytham, footfall is part of the plan: work is phased so shops and offices keep trading.

Wytham is about 4 miles north-west of Oxford, in Oxfordshire. Across the OX2 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Oxfordshire coverage takes in 423 places.

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Quoting for work in Wytham

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
  • The site’s rules and procedures
  • The size and state of each joint

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to ring 01277 525 020 or use the quote form.
