How we handle construction mastic in Bow
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. We work on cladding and panel joints, floor and skirting junctions and sanitary and kitchen joints, and what we’re called in for most is perimeter gaps outside the sealant’s range and frame perimeters left unsealed or poorly sealed. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Bow, preparation and product choice get the time they need.
For a site near Bow, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

When to call us in Bow
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. We flag them early rather than filling them with sealant that won’t last.
If one of these sounds familiar, it’s time for a closer look:
- Oversized or tapered gaps around new frames
- New external sealant already peeling away
- Frame perimeters left unsealed or poorly sealed
- Sanitary sealant damaged by following trades
New wings at hospitals like Longworth Hospital (3.9 miles west of Bow) bring long runs of window and panel joints to seal.
What your quote should include
- How they handle RAMS and site documents
- Proof of insurance
- Their plan for phasing and protecting the area
- Will CSCS-carded applicators be on site?
How the job changes by surface
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit, depending on what suits the programme.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Designing joint widths or choosing the specification (that sits with the designer)
- Joints damaged after sign-off by following trades
- Faulty frames rather than failed sealant
If you’re not sure, just ring 01277 525 020 or send details through our quote form and we will give you a straight answer.

New build and refits around Bow
Bow is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. Bow is about 61 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
Historic houses such as Longworth House (to the north-east of Bow) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. University estates such as University of Oxford, 4.3 miles north of Bow, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
Bow is about 4 miles east of Faringdon, in Oxfordshire. We cover Bow, with the same fixed quotes and 12-month guarantee as everywhere else. Our Oxfordshire coverage takes in 423 places. For work in that direction, see our Oxford page, about 14 miles away.
Commercial sites across SN7 are covered. Buildings on Chapel Road, High Street and Sheards Lane are within our area. Just outside Bow, we also work in Stanford in the Vale (1 mile west), Hatford (1 mile north-west), Shellingford (2 miles west), Baulking (2 miles south-west) and Buckland (3 miles north). Bigger towns within reach include Oxford (14 miles north-east), Didcot (11 miles east), Abingdon-on-Thames (10 miles east), Witney (10 miles north), Carterton (10 miles north-west) and Wantage (5 miles south-east).
Near you in Bow
Locally, jobs take us to sites close to Former Red Lion Public House and Holy Trinity Church, among other places. A little further out are Faringdon Museum (3.8 miles west) and Faringdon Castle (3.4 miles north-west).
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Bring the mastic contractor in after the last trades are through
- Ask installers to correct oversized gaps first
- Plan external elevations with the weather in mind
- Keep product details for future maintenance
After we have sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work.
From enquiry to sign-off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Bow need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Every joint is prepared, set to depth and sealed with the specified product.
- We close out snagging and hand over with a 12-month guarantee.
Before we start on site

What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
What accreditations do you hold?
We are CHAS accredited and a Constructionline member, and each applicator is CSCS-carded. Public liability insurance is in place.

Cost factors for mastic packages
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Induction, permit and paperwork requirements
- Working within restricted access windows
- Whether old sealant has to be cut out first
- Access and working height
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Details that help us quote
However big the job, the same details help:
- Where the site is, with the postcode
- The type of building and who uses it
- Specification clauses that apply
- Your programme or deadline
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email the details over.
