Facade sealing in Ashton, done properly
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. If you have new sealant peeling off old mastic and sealant pulling away from frames or panels, we can put it right, on perimeter joints where frames meet the structure, cladding panel joints and window and door perimeters alike. Searching for sealant specialists in Ashton? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Sites around smaller places like Ashton can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

What we’re called out for in Ashton
Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and tears as the joint moves.
It’s worth sending us details if you spot any of the following:
- Cladding panel joints that have opened up
- Water coming in around window frames
- Perimeter joints where frames meet the structure
- Unsightly perimeter sealant on a visible elevation
Units on estates such as Swanmore Business Park (to the south-east of Ashton) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Questions to ask before you book
- Their plan for phasing and protecting the area
- How the existing material will be dealt with
- Health and safety accreditation such as CHAS
- Will CSCS-carded applicators be on site?
Questions about Ashton
Will you take on work at estates like Swanmore Business Park, close to Ashton?
Yes, sites like Swanmore Business Park are within our area, along with the rest of Ashton. Photos and a short description are enough for a first look.
Can you take on a job at a hospital such as Moorgreen Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Do you cover Ashton?
Yes. Ashton falls within our area, and you can call 01277 525 020 or send details through our quote form to get started.
Contractors’ notes for Ashton
Ashton sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Ashton lies roughly 61 miles out 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.
School extensions, at buildings such as Bishops Waltham Infant School, usually run to the summer holidays, mastic included. For a contractor at a hotel such as The Crown Hotel (1.2 miles south of Ashton), the mastic often has to be finished before a reopening date.
Ashton is about 5 miles north-east of Hedge End, in Hampshire. Ashton sits inside our coverage and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. Ashton is one of 723 places we cover in Hampshire for facade joints. We also cover Southampton, some 8 miles away.

Around Ashton
Around Ashton, our work takes us to commercial buildings near Swanmore College of Technology, among other places. For rail, the closest station is Botley station, roughly 4 miles south-west. Nearby you will also find Bishop's Waltham Museum (1.1 miles south) and Moorgreen Hospital (5.3 miles south-west). Not far away are Beacon Hill and Bishops Waltham Branch LNR.
Why act early in Ashton
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts. Older rural buildings around Ashton move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Different surfaces, different methods
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint rather than the system it surrounds.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
Cost factors for facade joints
The price varies from site to site. It mainly depends on:
- Working within restricted access windows
- How accessible the joints are
- Whether old sealant has to be cut out first
- The product specified
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Sending details for a quote
To price the job accurately, we need to understand the site. Useful things to include:
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
- The site address and postcode
- The product your specification calls for
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email a schedule or drawings to discuss it first.
Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Rural sites near Ashton may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Arrange parking or a loading space
- Warn occupants and staff about the work
- Send any specification or drawings in advance
Request a quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or use the quote form with what you know.
Advice
What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Damaged frames that need replacing
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Replacing glass or failed glazing units
