After the work
To get the most from the new sealant:
- Record the product and colour used on each elevation
- Confirm the survey covers external sealants in older buildings
- Never let anyone seal over old sealant
- Add perimeter sealant to planned maintenance checks
Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
Facade sealing in Hunton
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you’re dealing with failed sealant on precast panel joints and previous reseals run over old sealant, we can put it right. Looking for mastic applicators who cover Hunton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
For a site near Hunton, 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, photographs and the programme let us give a fixed quote.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Your questions answered
Is Hunton too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can work at a site such as University for the Creative Arts - Maidstone fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is your workmanship covered by a guarantee?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Can you find out why a window is leaking?
Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Is old mastic on our building likely to contain asbestos?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, and we will ask to see it. Suspect material is left alone until it has been tested.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
Signs you need facade sealing in Hunton
The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Any of the following is a good reason to get the joints checked over:
- Failed sealant on precast panel joints
- Patch repairs that keep failing
- Perimeter sealant that has split or peeled away
- Leaks at window and door perimeters
New wings at hospitals like Oakwood Hospital (3.7 miles north of Hunton) bring long runs of window and panel joints to seal.
What to look for in a quote
- Whether old or failed sealant will be cut out, not overlaid
- The terms of the workmanship guarantee
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
Owners, agents and contractors
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Surface by surface
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints, not the framing or glazing itself.
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and areas needing repair are flagged.
Facade sealing in Hunton: the local picture
Hunton is about 31 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, Hunton included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
School extensions, at buildings such as Hunton Church of England Primary School, typically run to the summer holidays, mastic included. University estates such as University for the Creative Arts - Maidstone, 4 miles north-east of Hunton, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
Hunton is about 4 miles south-west of Maidstone, in Kent. We cover Hunton, with the same fixed quotes and 12-month guarantee as everywhere else. Hunton is one of 931 places we cover in Kent for facade joints. London is covered too, some 31 miles away.

Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Hunton are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Before we start on site
- Move anything stored against the joints
- Send any specification or drawings in advance
- Arrange parking or a loading space
