Mastic sealing for Holywood sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Leaks through the frame itself rather than the perimeter
- Misted or failed double-glazed units
- Materials that need asbestos testing before work
If you’re not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer before you book.

How we handle mastic sealing in Holywood
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on external wall and movement joints, communal kitchens and washrooms and window and door perimeters on blocks, and what we are called in for most is occupiers reporting cold air round windows and mastic failing across several blocks on an estate. Looking for mastic applicators who cover Holywood? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around smaller places such as Holywood, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Exposed walls take Scottish weather hard, and frame mastic shows it first.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Plan resealing building by building rather than complaint by complaint
- Encourage occupiers to report problems at frames
- Make mastic part of routine maintenance checks
- Keep a record of when each building was resealed
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
Why it’s worth doing now in Holywood
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Around smaller places like Holywood, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Common questions from Holywood clients
Can you quote for a block close to Dumfries station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Holywood too small for you to travel to?
Not at all. Holywood is within our area. We cover the whole of Scotland. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can you reseal a whole block or estate?
Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
