Gutter Guards

What do you call them? 
Leaf screen, gutter guards, leaf protection, debris filter?

Gutter Clean System® gutter guards are designed to be easier to maintain by letting the wind do most of the heavy lifting. Because their surface is made of perforated aluminum, debris sits on top, dries out, and is carried off by the breeze. Alu-Rex guarantees your gutters will stay clog-free for 40 years.

Our Satisfied Customers

The house looks AWESOME – I can’t believe the difference this has made. It turned out really well – looks even better than we imagined it would. And THANKS for getting it done so quickly. We appreciate getting to watch the rain without needing rubber boots in the family room.

Rick and Shelley Pyra

Thunder Bay, Ontario

We chose All Season Siding and Windows on the recommendation of a friend and found their quotation to be the lowest of two. The work was begun when promised and completed to our entire delight. The job was fantastic, the staff friendly, hard-working and professional. The finer work they did on some corners and attention to general detail is above average and far exceeded our expectations. We are very pleased with the look of our home now and do not hesitate to recommend All Season Siding and Windows to anyone.

Jo-Ann and Clyde Jacomb

Thunder Bay, Ontario

We hired All Season Siding and Windows to do the siding on our home. The quote was competitive and they started and completed the project right on schedule. They did a great job on the house – it looks fantastic. They worked really diligently to keep the yard clean and free of debris at the end of each work day and they even hauled away all the old siding. Fantastic job All Season! I would highly recommend you!
