Tech-Dry Building Products
Their DPC cream is specifically credited with fixing a long-standing rising damp problem.
What the reviews suggest most clearly is that staff know their products well enough to point customers toward the right solution, not just sell them something off the shelf. If you're dealing with rising damp and want to explore a product-based fix, it's worth calling them directly to describe your situation and see whether their approach fits your problem — and ask whether they supply to DIYers or work primarily with trades.

About Tech-Dry Building Products
Tech-Dry Building Products focuses on damp-proofing and waterproofing solutions, with their DPC (Damp Proof Course) cream product drawing specific mention from customers as a remedy for rising damp — a problem that many older homes in the Penrith region face due to aging brick and mortar construction. Rather than a pure trade service, the business appears to operate at the intersection of product supply and technical advice, offering homeowners both the materials and the know-how to address moisture problems. Reviewers highlight that staff pair a solid product range with genuine knowledge, suggesting you're not just buying off a shelf but getting guidance on what will actually work for your specific damp issue. With around five years of operation, they've had time to develop a focused offering rather than a broad-brush waterproofing service. They're likely best suited to homeowners tackling persistent damp problems — particularly rising damp in older properties — where a targeted product-based solution is more practical than a full structural remediation.
Best for: homeowners dealing with long-term rising damp in older properties, buyers seeking product-based damp-proofing solutions with expert guidance, and those looking for DPC cream or targeted waterproofing materials in the Penrith area.

What type of damp problems does Tech-Dry Building Products address?+
Based on customer reviews, their DPC cream is specifically mentioned as an effective treatment for rising damp — the kind of moisture that wicks up through masonry from the ground. This is a common issue in older Penrith-area homes with aging mortar or absent damp-proof courses. Reviews don't mention other damp types like penetrating damp or basement flooding, so it's worth calling them to confirm whether your specific issue falls within their product range.
Does Tech-Dry supply products for DIY use or only work with tradespeople?+
The reviews don't clarify whether they sell direct to homeowners or primarily supply trades and builders. Given that customers appear to have purchased and used the DPC cream themselves, there's a reasonable chance they cater to both — but confirm this directly when you contact them, especially if you're planning to apply the product yourself.
What do customers say about the knowledge level of the staff?+
One reviewer specifically noted a 'great product range with the knowledge to match,' which suggests staff can guide you toward the right product rather than leaving you to figure it out alone. With only 4 reviews to draw on, this is a promising signal but not a large enough sample to say it's universally the case. It's worth asking specific questions when you call to gauge how well their advice maps to your situation.
Does Tech-Dry Building Products operate out of a physical location in Penrith?+
They're listed as an establishment and point of interest in Penrith, NSW, which suggests they have a physical presence rather than being purely mobile. However, reviews don't describe a shopfront visit or delivery experience in detail. Contact them directly to confirm whether you can visit in person, arrange delivery, or need a site consultation.
How long has Tech-Dry Building Products been operating?+
The business has been active for approximately five years, which suggests it's past the very early startup stage. That said, with only 4 Google reviews accumulated over that period, they haven't built a large public review footprint — which may mean they work largely through referrals or trade channels rather than direct-to-consumer marketing.
