Construction & Renovation Services

Whether you’re renovating an existing home or building out a new space, we keep the project moving so you can get back to what matters most.

Kitchen Remodeling in Mandeville, LA

Mandeville kitchens vary considerably depending on the age and type of the home. The older cottages near the lakefront tend to have character that is worth preserving, which requires a more thoughtful approach to renovation than a straightforward gut and rebuild. Newer homes in the subdivisions north of town often have better infrastructure but builder-grade finishes that do not reflect the investment homeowners have made in the property. We work on both. Our kitchen remodeling projects in Mandeville are designed around the specific home and the specific homeowner, not a standard package applied uniformly.

Bathroom Remodeling in Mandeville, LA

Bathroom renovations in Mandeville are in consistent demand, and we have built a reputation for quality work in this market. Mandeville homeowners tend to want master bathrooms that feel like a genuine retreat — large custom showers, soaking tubs, quality tile throughout, and lighting that works. We have delivered all of that for clients in this area. We also handle smaller scope bathroom projects with the same professionalism, because a well-done hall bathroom or guest bath refresh matters too. Every bathroom we complete in Mandeville is finished the way we would want our own bathroom finished.

Whole Home Renovation in Mandeville, LA

Mandeville homeowners who invest in whole home renovations are typically motivated by a clear vision of what their home could be and a recognition that getting there requires a comprehensive approach rather than a series of small projects. We have executed whole home renovations throughout Mandeville that involved every major system and finish in the home, coordinated through St. Tammany Parish’s permitting process and managed by a single team accountable for the full outcome. The result of a well-executed whole home renovation in Mandeville is a property that functions and looks exactly as it was designed to — cohesive, high-quality, and built to last.

Home Additions in Mandeville, LA

Home additions in Mandeville are particularly popular for families who want more space in a city they are committed to living in long-term. We have built additions throughout Mandeville, including expansions of lakefront properties where the existing footprint did not make full use of the view or the setting, and more conventional rear additions on residential lots in the newer subdivisions. We handle the feasibility review, the permitting process with St. Tammany Parish, and the full construction scope from foundation work through finish.

Frequently Asked Questions

What renovation and construction services does Quillen Construction Group offer in Mandeville?

We offer kitchen remodeling, bathroom remodeling, whole home renovations, home additions, general contracting, and commercial construction services throughout Mandeville and St. Tammany Parish. We work on properties across the full range of Mandeville’s housing stock, from historic cottages near the lakefront to newer custom builds in the subdivisions north of downtown. Every project we take on in this market is approached with the quality standard Mandeville homeowners expect.

Are you experienced working on lakefront and waterfront properties in Mandeville?

Yes. We have worked on properties along the Mandeville lakefront and in waterfront settings throughout the Northshore. These properties often involve specific construction considerations — elevated foundations, marine-grade materials in exposed areas, permitting requirements related to proximity to the water — and we are familiar with all of them. If your property has waterfront characteristics that affect the renovation scope, we factor those into the project planning from the beginning.

How does Quillen Construction Group approach bathroom renovations in Mandeville?

Master bathroom renovations in Mandeville tend to be high-scope projects where homeowners want a meaningful upgrade in both function and finish quality. We start with a detailed design conversation to understand exactly what you want — the shower configuration, the tile selection, the vanity style, the lighting scheme — and we build the project plan around that vision. We do not use cookie-cutter bathroom packages. Every bathroom we build in Mandeville is designed and executed as a specific project for a specific client.

What should I know about home additions in Mandeville before getting started?

A few things are worth understanding upfront. St. Tammany Parish has setback requirements that limit how close a structure can be to property lines, which affects what additions are feasible on a given lot. Flood zone status affects what is permissible and at what elevation for properties in certain areas. And additions to older homes may require structural upgrades to the existing foundation or framing before the new square footage can be safely built. We assess all of these factors during the initial site visit so you have a complete picture before committing to a scope.

Does Quillen Construction Group serve the entire Mandeville area including subdivisions north of downtown?

Yes. We serve all of Mandeville, including the historic areas near the lakefront, the older neighborhoods in the original town grid, and the newer subdivisions that have developed north and west of downtown over the past two decades. Distance within the city is not a factor. Call us at (504) 800-4126 to schedule a site visit anywhere in Mandeville.
