About our construction mastic in Little Wittenham
Mastic tends to be one of the final packages before handover. We work as a mastic subcontractor to main contractors and developers with projects in Little Wittenham, sealing plot by plot or floor by floor as areas are released. If you have existing joints on a refurb that need cutting out and resealing and sealant knocked or painted over by other trades, we can help, on window and door perimeters, cladding and panel joints and floor and skirting junctions alike. Whoever orders the work in Little Wittenham, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Conversions of older rural buildings near smaller places such as Little Wittenham bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Honest limits
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Joint design decisions that belong to the architect or engineer
- Frames fitted out of tolerance
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly.
What we seal
- Cladding and panel joints
- Internal decorators’ caulk
- Window and door perimeters
- Brick and block movement joints
- Sanitary and kitchen joints
- Floor and skirting junctions
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Signs you need construction mastic in Little Wittenham
Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. Better to raise it at the start than seal a joint that’s bound to fail.
Common reasons buildings call us in:
- Caulk cracking where joints are moving more than expected
- Missed perimeter joints on a new elevation
- Frame gaps too wide for sealant alone
- Sanitary sealant damaged by following trades
Projects at schools like Long Wittenham (Church of England) Primary School work to term dates, so mastic is programmed tightly.

How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and our waste is bagged and taken away as we go.

What else we do in Little Wittenham
Your questions answered
Is a smaller place like Little Wittenham outside your area?
No. Places such as Little Wittenham are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work at a site such as Southmead Industrial Estate, by Little Wittenham?
Yes. Our area takes in Little Wittenham and its surroundings, with estates and business parks such as Southmead Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Do your applicators hold CSCS cards?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you work plot by plot or floor by floor?
We follow the trades through the building. Areas are sealed as they’re released by the site team and we tell you if something stops an area being sealed.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Looking after the joints
A few simple habits keep the new joints working:
- Don’t force external sealing on a damp or frosty day
- Ask installers to correct oversized gaps first
- Use the product the specification names
- Record the products used in the O&M file
Record which products went where in the handover file. Future maintenance is easier when the products are known. Tell us what records you need and we will confirm with the quote.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We flag them as soon as we see them.
Quoting for work in Little Wittenham
Quotes vary with the job. It mainly depends on:
- Site requirements such as inductions and permits
- Joint width, depth and condition
- Working within restricted access windows
- How much existing material needs removing
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- Rough lengths or quantities, or drawings if you have them
- The asbestos register, for older buildings
- How the joints are reached, and at what height
- Photos of the joints, close up and from further back
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, phone 01277 525 020 or use the quote form.
New build and refits around Little Wittenham
Little Wittenham 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, so we time external mastic for dry faces and agree it with the site team. At about 48 miles from central London, Little Wittenham is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
For a contractor at a hotel such as The George Hotel (1.1 miles north-east of Little Wittenham), the mastic often has to be finished before a reopening date. Units on estates such as Southmead Industrial Estate (2.9 miles west of Little Wittenham) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
