"When JDS Masonry, Inc. decided to build a new office building, we chose AL Droste & Sons Construction to head the project as the general contractor. Their knowledge of construction is second to none. Droste's reputation of honesty and integrity gave me peace of mind through the whole building process. I would not hesitate to recommend them to anyone and will use them in any future endeavors."

Al Droste and Sons Construction takes pride in being the oldest general construction company in St. Charles County. For over 85 years, our company has built its reputation with a wide range of unique projects, a loyal and repeat customer base, and an attention to detail and craftsmanship.

With current third generation owner, Jim, and fourth generation sons - Nate and Jeff, Droste Construction is committed to the same quality, craftsmanship, and attention to detail that Alvin Droste built his reputation on.

We are experienced in new construction, remodeling, and additions for both commercial and residential, as well as historic preservation and renovations. We keep a core, loyal team of in-house carpenters, subcontractors, and suppliers who adhere to our high level of quality and provide excellent customer satisfaction at a competitive value.



Be it your company's expansion or relocation, your first or second home, needed historic restoration, or just updating your business or home.

We recently moved our dental office and used Al Droste & Sons Construction. They were great to work with, very reliable, efficient, and trustworthy. Our office turned out great! I would definitely use them for any future projects and highly recommend them!
