About our construction mastic in Sibford Ferris
On a new build, the mastic package is one of the last trades through each area. Mastic Doctor takes on mastic packages for main contractors and developers with projects in Sibford Ferris, sealing plot by plot or floor by floor as areas are released. Most enquiries involve window and door perimeters that won’t pass inspection and existing joints on a refurb that need cutting out and resealing, across window and door perimeters, sanitary and kitchen joints and cladding and panel joints. One point of contact handles commercial sealant work in Sibford Ferris from the first photos to the final walk-round, for single jobs and planned programmes alike.
For a site near Sibford Ferris, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

New build and refits around Sibford Ferris
Sibford Ferris is about 70 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
Historic houses such as Broughton Castle, 3.8 miles east of Sibford Ferris, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Projects at schools like Sibford School work to term dates, so mastic is programmed tightly.

Doing it in-house
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Looking after the joints
A few simple habits keep the new joints working:
- Record the products used in the O&M file
- Share drawings and the specification as soon as possible
- Stick to the specified sealant rather than a generic substitute
- Release areas for mastic once other trades have finished in them
Record which products went where in the handover file. Future maintenance is easier when the products are known, and tells you what to reseal with. We can confirm the handover information you need when we quote.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels. Proper preparation, with the right silicone first time, keeps it off the defects list.
Leave it or put it right?
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal and that’s a far smaller job. If the frame is life-expired, we will tell you. Converted and older buildings near places like Sibford Ferris tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Common questions from Sibford Ferris clients
Can you work to our programme on a site in or near Sibford Ferris?
Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Sibford Ferris off your patch?
Not at all. Sibford Ferris is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Does weather matter for sealant work?
For external joints, 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.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Does weather affect external mastic work?
Weather matters for external sealing: each sealant has a temperature range, and the joint must be dry. External work is sequenced with some flexibility.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Common problems we fix in Sibford Ferris
A new building moves while it dries and settles. Materials lose construction moisture and shrink. Picking a flexible sealant where there’s movement keeps snags down.
Common reasons buildings call us in:
- A mastic package split between trades with no clear owner
- Caulk cracking where joints are moving more than expected
- Existing joints on a refurb that need cutting out and resealing
- A long mastic snag list close to completion
Recladding or extending a unit at a site like Brailes Industrial Estate (to the north-west of Sibford Ferris) brings panel joints and frame perimeters into the programme.
Before you book anyone
- Their plan for phasing and protecting the area
- What site paperwork they can supply
- What level of public liability insurance do they hold?
- How the joint faces will be prepared and primed
