Construction mastic in Great Western Park, done properly
Mastic Doctor has been a subcontractor on construction projects for over 20 years. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Great Western Park, send drawings and the specification through our quote form. We work on window and door perimeters, sanitary and kitchen joints and floor and skirting junctions, and the failures we are asked to look at most are external joints sealed in damp or cold conditions that are now failing and snag items on joints that need redoing before handover. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Great Western Park is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Building work in places the size of Great Western Park is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Leave it or put it right?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Small buildings around Great Western Park suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What you get with us
- Products installed to the manufacturer’s instructions
- CHAS accredited
- Old sealant cut out, never sealed over
- Sealing commercial buildings since 2005

Surface by surface
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it and work only when conditions suit.
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
New build and refits around Great Western Park
Great Western Park sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. A number of hotels sit less than 2 miles from Great Western Park. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
When units on a site such as Trident Business Park, 1.1 miles north-east of Great Western Park, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Older buildings in the area around Great Western Park, such as Clifton Hampden Manor (4.4 miles north-east of Great Western Park), need care when sealed: the product has to suit soft or historic materials. For a contractor at a hotel such as The Kingswell Hotel, which lies south-west of Great Western Park, the mastic often has to be finished before a reopening date.

Questions we’re asked in Great Western Park
Can you work at a site such as Trident Business Park, by Great Western Park?
Yes. Estates, retail parks and business parks around Great Western Park, Trident Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is a hospital such as Didcot Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
What accreditations do you hold?
CHAS and Constructionline are both in place, and our applicators hold CSCS cards. Public liability insurance is in place.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Flag uneven or tapered frame gaps early
- Note which sealant went where at handover
- Brief following trades on areas that have been sealed
- Don’t force external sealing on a damp or frosty day
After we’ve sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked; we confirm the time for each product.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
What affects the price in Great Western Park
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Travel to remote or island sites
- Whether the work must be split into stages
- The site’s rules and procedures
- Quantities, in metres or numbers
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What to include in your enquiry
However big the job, the same details help:
- Your programme or deadline
- Photos of the joints, close up and from further back
- The type of building and who uses it
- The product your specification calls for
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email a schedule or drawings.
