When it rains, it pours! So when you’ve just finished up work on a new garden project, you want to make sure it’s protected against the wet and damp that could ruin all your hard work.
You don’t want that new shed rotting over time, or for that concrete patio you just laid to become slimy and discolored. You want your garden efforts to pay off year after year, so you can keep on enjoying your outdoor space without any more effort.
That’s why you might want to invest in exterior waterproofing. When your surface materials are properly sealed and coated, bad weather won’t ruin the view!
And if you’re looking for an experienced professional to weatherproof your garden for you, we’ve got just the company: Capital Deck & Stair Waterproofing.
Here’s an honest review of their waterproofing services in 2025.
Capital Deck & Stair: A Waterproofing Company with Over 40 Years Experience
Based in Los Angeles, Capital Deck & Stair Waterproofing are the weather protection experts.
Serving an area that’s about 50 miles wide around LA, their portfolio has grown extensively at this point.
They’ve been in the business for over 4 decades now, and their team has a wealth of skill and knowledge that’s hard to find in other outdoor contractors.
They offer a lot of quality in their waterproofing services, and it’s not hard to see this quality come through in their project images alone.
Their Waterproofing Services
As the namesake of Capital Deck & Stair Waterproofing, the amount of waterproofing services on offer shouldn’t come as a surprise!
Here are the kind of projects they specialise in:
Decks
From the deck outside your back door to your front porch, as well as any walking decks that cover ground across greater areas of your garden, deck projects form the bulk of the company’s waterproofing.
After all, most decks are made of wood or wood composites. If they’re not properly waterproofed, the material is going to break down through damp, water logging, and even a bit of rotting!
Pool decks
Speaking of decks, this is another speciality in Capital Deck & Stair Waterproofing’s arsenal!
If you’ve just had a pool put in your back yard, make sure the deck around it has been properly protected against the sloshing and splashing it’s likely to see!
Even just walking on a pool deck with wet feet can cause damage. If you want your summer addition to last a whole lot longer (even up to 5 extra years or more), get some sealant applied.
Balconies
Balconies can easily become filled with water, especially if the railings don’t allow anything to escape.
Indeed, if you’ve got brick walling around the edge, the water is going to sit and hopefully evaporate over the next couple of hours.
But there’s no guarantee, especially if the whole day has been mild, wet, and chilly.
Staircases
Exterior staircases take a pounding over time, and not just from the feet that go up and down them!
The wind and rain is going to cause a lot of water damage to them when there’s no proofing coated on top.
Outdoor stairs need to be safe, slip resistant areas. With waterproofing, not only will your steps be abrasive enough to prevent accidents, but the water is going to run right off as well.
Landings
Exterior landings are more common in commercial properties, and Capital Deck & Stair Waterproofing do cover both residential and commercial clients.
But outdoor landings can exist in homes too, particularly in properties that have a detached garage or other kind of outbuilding.
Get your landing waterproofed for safe traversal at all times.
