Mastic sealing in Prestonfield
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Why deal with it now?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. In a tenement or shared city building, water from a failed joint can reach other owners’ property, which makes early repair simpler for everyone. Acting early avoids disputes and bigger repairs.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Mastic sealing in Prestonfield, done properly
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. We work on external wall and movement joints, window and door perimeters on blocks and shopfronts below residential blocks, and what we’re called in for most is the same joint failures repeated across a portfolio and no planned programme for sealant. A single leaking joint is often how a building in Prestonfield first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Sandstone tenements in most Scottish cities, and granite in Aberdeen, need mastic that suits the stone, so perimeter mastic around replacement windows has to be neutral-cure and kind to the masonry.
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.

Quoting for work in Prestonfield
We price every job individually. The main factors are:
- Backing rod, priming and other preparation
- Site requirements such as inductions and permits
- Location, for remote and island sites
- The product specified
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Asbestos survey details if the building is older
- Clear photographs of the problem areas
- The type of building and who uses it
- Rough lengths or quantities, or drawings if you have them
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For premises in Prestonfield, tell us about access times, shared entrances and any building rules, and we will plan the work to suit, phased where areas need to stay in use.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Preparing the site
- Point out parking and an unloading spot
- Let us know about inductions and permits
- Warn occupants and staff about the work

Advice
Common problems we fix in Prestonfield
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Typical triggers for a call:
- No planned programme for sealant
- Draughts at frames across a block
- Communal area joints that look neglected
- The same joint failures repeated across a portfolio
For agents with blocks near Edinburgh Waverley station, 1.7 miles north-west of Prestonfield, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Questions to ask before you book
- The named product and why it was chosen
- Will RAMS and insurance details be available?
- What level of public liability insurance do they hold?
- Whether old or failed sealant will be cut out, not overlaid
Questions about Prestonfield
Can work in a care setting near Prestonfield go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.
Who do we deal with for shared-part sealing on a tenement in Prestonfield?
Work on shared parts is usually agreed by the owners, often through a property factor. We are happy to deal with the factor directly.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Different surfaces, different methods
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Substrate edges that need repairing first
- Broken glass or failed sealed units
- Water coming in from the roof or rainwater goods
If you are not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer before you book.

With the shore within about 3 miles, Prestonfield counts as a coastal location. On buildings near the shore, the side facing the weather normally needs its mastic renewed first, and they deserve more regular inspection. Prestonfield has six care or nursing homes no more than 2 miles away. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
If you are responsible for a building such as Priestfield Parish Church, frame and door mastic needs the same attention as any other property. Property owners at sites such as Peffermill Industrial Estate, 0.6 miles east of Prestonfield, can have mastic renewed between lettings.
