Summer News - Calling all Landlords

Now the summer is finally here this is the time to rectify all those mould problems, using Passyfier® Vent Kits, Extractor Fans, Fungicidal Washes, Anti-Mould Paints etc., that you have been putting off during the winter/spring period, whilst the weather is in your favour.

It's always interesting to hear people saying to us, "Do you actually carry the stock shown and when will delivery be?". When we reply and say, "the goods are on next day delivery and how many pallets do you want?", there is always a silence! But, joking aside, we do sell one offs to pallet orders and most importantly you do have to speak to a human before placing an order, who will give you advice should you need it!

April & May News - Spring Is In The Air

In March we saw an unprecedented increase in new customers coming to us (Over 60% of these new customers were recommendations, a statistic any politician this May would be jealous about!) for all sorts of products, and we are looking forward to this continuing.

Now spring is in the air it's the time to do a proper clean down of all that mould using a fungicidal wash, then paint the external walls internally using an anti-mould paint. Oh, and if you do not want just white anti-mould paint, we can tint to any pastel shade you want as long as you give us a Dulux paint reference.

Sorted then? Well not quite! Let's not forget about the top end of condensation control ventilation which can be accommodated via extractor fans with automatic humidity detection to kitchens and bathrooms and Passyfier® Vents which, act as an exhaust - without the dreaded draught - to release all that trapped water vapour in bedrooms, living rooms, dining rooms etc., thus aiding humidity control.
