Our Services
"We Spot the Problems Before You Sign."
Buying and renovating in Portugal can be risky — especially when you don’t know what’s behind the walls.
We work independently to protect your interests, offering honest, expert advice in plain English. As experienced builders, we spot costly issues early, so you can buy with confidence and avoid expensive mistakes.
Not just Porto.
Based in Porto, but available across Portugal — including Lisbon, the Algarve, and more. Travel fees apply outside the Porto region.

“I highly recommend Bradley Cahill if you’re looking for a building inspector in Porto or Matosinhos. I found him through the Porto Expats group, and I’m so glad I did.
Brad did a thorough inspection for me on very short notice, and honestly, it gave me huge peace of mind. He flagged potential problem areas, explained everything clearly, and was incredibly professional and friendly throughout the process.
He delivered a detailed report with recommendations and follow-up questions — which helped me handle a very stressful situation. If you’re feeling overwhelmed about buying a property here, I couldn’t recommend Bradley more.”

“Shoutout to Bradley Cahill for his professional service as a property inspector during our recent real estate inquiry in Porto.
He’s not just a building inspector — he’s a builder himself and an expat, which made a huge difference. His pricing was fair, and the feedback he provided on our potential purchase was exceptionally detailed and clear.
Hopefully, you won’t get too busy for future collaborations — we’d absolutely work with you again!”

"Highly recommend Brad and his team. We needed a last-minute building inspection before committing to a property in Porto, and Brad made time for us — even after hours. He was thorough, incredibly helpful, and patient with all our questions as nervous first-home buyers. His advice and insights gave us real confidence. Brad’s hard to book for good reason — his work speaks for itself. Thanks, mate — looking forward to working with you again on the deck!"
