Facade sealing in Wallingford
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Leave it or put it right?
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Small buildings around Wallingford suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Why us?

- Fully insured, including public liability cover

How we handle facade sealing in Wallingford
We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds, using sealants classified for facade or glazing use. We work on stone and brick facade joints, coping and flashing joints and shopfront frames, and the usual reasons a site gets in touch are leaks at window and door perimeters and failed sealant on precast panel joints. A single leaking joint is often how a building in Wallingford first comes to us: we look at the rest while we are there and tell you what we find.
On a small site around Wallingford, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What sets the cost
We price every job individually. The things that drive the figure:
- Distance, for remote addresses
- Working within restricted access windows
- Induction, permit and paperwork requirements
- Specialist products, such as fire-rated or hygienic sealants
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
What we need to price the job
However big the job, these details speed things up:
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
- The type of building and who uses it
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email drawings and photos.
Different surfaces, different methods
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed using a sealant classified for that use.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather and need a durable external sealant.
Our process
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Work in places the size of Wallingford is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- Access, site rules and timing are settled with the client up front.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
Before we start on site
- Confirm the product named in the specification
- Point out any areas we must not close
- Point out parking and an unloading spot

Questions about Wallingford
Is Wallingford off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Do you take on work at healthcare sites like Wallingford Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you replace failed glazing units?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. That is what makes the new joint last.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Contractors’ notes for Wallingford
Several hotels sit less than 2 miles from Wallingford. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Wallingford sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
With historic properties like Brightwell Manor, 1.7 miles to the north-west of Wallingford, in the area, refurbishment work often meets old masonry that needs compatible sealants. Work at a hotel such as The George Hotel, less than half a mile east of Wallingford, tends to be programmed around bookings, mastic included. New units and refits on sites such as Hithercroft Industrial Estate (under half a mile south-west of Wallingford) need their panel and perimeter joints sealed to the specification.
