Lakehouse Renovation 101

Revamping and updating your waterfront property — what to prioritize, what to watch out for, and how to find the right contractor

January 25, 2025LakehomeResource.com9 min read

Renovating a lake home is one of the most rewarding projects a property owner can undertake — and one of the most complex. The combination of an older building stock (many Michigan lake cottages date from the mid-20th century), a demanding natural environment, shoreline regulations that restrict what can be changed, and the unique demands of how a lake home is actually used creates a renovation landscape that differs meaningfully from a standard residential remodel.

Here are the five phases and principles that every successful lakehouse renovation shares.

1

Assess Before You Plan

Before drawing a single line or visiting a single showroom, spend time living with the property. Understand how light moves through it at different times of day. Identify what genuinely bothers you and what works. Map out how you actually use the space versus how you imagined using it. The most common renovation mistake is addressing aesthetic problems when the real problem is functional — a layout that does not work, sightlines that do not connect, traffic flow that creates constant friction.

2

Prioritize the Lake Connection

If your renovation budget is limited, spend it on the moments of connection to the water. A sliding glass wall where a solid wall existed. A screened porch that extends living space outdoors toward the lake. A master bedroom window relocated to capture the morning water view. Structural improvements that create better lake connection have more lasting impact on how you experience the property — and on its value — than any cosmetic renovation.

3

Hire the Right Contractor

Lakefront renovation requires contractors who understand the specific conditions: high humidity effects on materials, shoreline permit requirements, the challenges of delivering materials to water-access properties, and the structural considerations of homes that experience freeze-thaw and ice-push forces. Ask for references from lakefront projects specifically. A contractor's track record on standard residential work tells you very little about how they'll perform on a waterfront property.

4

Plan for Durability, Not Just Aesthetics

The lake environment is hard on materials. UV exposure, humidity, seasonal expansion and contraction, salt (if near Lake Michigan), and the general hard use of an active vacation property all accelerate deterioration. Choose finishes rated for outdoor or high-humidity environments even in interior spaces near the water. Solid wood cabinetry, exterior-grade hardware on windows and doors, and moisture-resistant flooring are not over-engineering — they are appropriate specifications for the environment.

5

Budget for the Unexpected

Lake homes, particularly older cottages, are full of surprises behind the walls. Old wiring, outdated plumbing, insulation from a previous generation, posts set in the ground without footings, previous owner repairs that looked fine from the outside. Add 20% to any renovation budget as a true contingency — not 10%, not 15%, but 20%. Experienced contractors working on older lake homes routinely tell clients to expect discoveries, and the ones who planned for it are far less stressed when they happen.
