Common Questions
What are the main differences between modular and manufactured home construction you offer?
While both are efficient building methods, modular homes are constructed in sections in a factory to local building codes and assembled on your permanent foundation, offering more design flexibility. Manufactured homes, built to a federal HUD code, are transported as a complete unit. Grenadier Construction can guide you through the site preparation, delivery, and setup for both, ensuring a seamless process tailored to your needs and Jefferson County regulations.
How do you help Watertown homeowners prevent outdoor faucet freezing and hard water damage?
We address the common local issues of freezing faucets and hard water buildup directly. For freezing, we can install frost-free sillcocks and properly insulate vulnerable lines. For hard water, we recommend and install whole-house water softeners or point-of-use filters to protect your plumbing fixtures and appliances from scale buildup, extending their lifespan and improving efficiency.
Do you handle the entire process for building a guest house or ADU on my property?
Yes, Grenadier Construction manages the complete ADU project from start to finish. This includes initial consultation and design, navigating local Watertown zoning and permit requirements, all phases of construction, and final inspections. Our experience ensures your accessory dwelling unit is built correctly, on time, and meets all legal specifications for rental or family use.
