How We Approach Every Building Job in Cork

Every job starts with a proper site visit. No quoting over the phone for work we haven’t seen — that’s how corners get cut and clients end up disappointed. We assess the scope, explain exactly what’s involved, and give you a clear written quote with no surprises.

Plastering, Dry Lining & Damp Proofing

Moisture is the root cause behind most interior wall failures in Cork homes — particularly in older terraced and semi-detached properties. We identify the source before any remedial work begins. Damp proofing treatment goes in first; plastering and dry lining follow once the wall is properly dry. That sequencing matters. Skipping it, or letting a plasterer work over a damp wall, means you’ll be back dealing with the same problem in 18 months. We don’t operate that way.

Paving, Fencing & Retaining Walls

Outdoor work requires proper groundwork — and that’s where a lot of tradesmen cut corners. Our paving teams prepare sub-bases to spec, our drainage work complies with EPA guidelines for Cork, and our fencing goes in correctly the first time. We also handle steam cleaning before any paving or surfacing project to ensure proper adhesion and a clean finish.

Drainage Systems & Steam Cleaning

Drainage problems tend to get ignored until they cause serious damage. We design and install drainage systems that comply with EPA guidelines for Cork, whether that’s surface water management, soakaway installation, or redirecting existing systems that aren’t working. Steam cleaning is typically the starting point for any paving or surfacing project — it strips back contamination and ensures proper adhesion. We don’t lay anything over a dirty or compromised surface.

Questions About Our Building & Renovation Services in Cork

Do I need planning permission for building renovation work in Cork?

Most internal renovation work — plastering, dry lining, damp proofing — doesn't require planning permission. External work like paving, retaining walls, and fencing also typically falls within exempted development thresholds. We'll advise you during the site visit if anything you're planning does require permission.

How long does renovation work typically take in Cork?

It depends heavily on the scope. A plaster re-skim might take a day or two. A full damp proofing treatment with re-plastering of an affected room typically takes 3–5 days. Larger outdoor projects like paving a driveway or installing drainage systems can take 1–2 weeks. We'll give you a realistic timeframe in the quote.

Are you able to handle multiple trades on a single renovation project?

Yes. Keystone Roofing has tradesmen across all the services listed on this page - plastering, damp proofing, paving, fencing, drainage, and more. If your project involves multiple trades, we coordinate everything so you're not managing multiple contractors yourself.

Do you offer free quotes for building and renovation work in Cork?

Yes, always. All our quotes are free, given after an on-site visit, and written up clearly so you know exactly what you're getting and what it costs. Call us on 087 223 4228 or use the contact form to arrange a visit.

Can you treat rising damp and then re-plaster the same room?

Yes - and this is actually the right way to approach damp problems. Treating damp and then plastering straight away is pointless; the moisture needs time to clear. We time the works properly, so your new plaster goes on over a properly treated, dry wall. No shortcuts.
