Deck & Railing

we have been building decks for over 30 years. If you want your new deck, replacement deck or deck repair done right the first time you have come to the right place.


We take great pride in building the highest quality fencing. Our pledge to you is we will use the highest quality hand selected fence building materials available.


I have been a house framer for over 25 years. I spent eight years working under a master carpentercontractor. In those years we built over thirty custom homes.


At A-1 Construction we believe that every deck needs a pergola. When the thermometer hits 90 degrees and up a deck becomes the hottest place in the yard.

Retaining Walls

If you don't like the standard look of a retaining wall we can dress it up with shingles. Or we can put the wall boards on the outside of the wall.


If you need new stairs you've come to the right place. At A-1 Construction we understand stairs from the top to the bottom and inside out.

Water Damage Restoration

Water damage is usually caused by water penetrating the homes outer surfaces like the roof, windows, doors, siding, stucco, shower or a toilet over time.

Windows & Doors

We replace old aluminum, steel or wood framed windows. If your home is stucco the best choice in most cases is a Z framed replacement window.
