Picking a contractor for a remodel usually comes down to scope. Some companies focus on one area of the home, others handle both interior and exterior work, and a few are set up to manage design and construction together from the start. Knowing which lane a company works in before you call can save you from wasting time on estimates that do not fit the project.
St. Louis has a deep bench of remodeling companies, and the differences between them matter more than the glossy project photos suggest. Below are six worth knowing, starting with a contractor built around both exterior and interior work.
Best for Combined Exterior and Interior Remodeling – Lakeside Renovation & Design
Lakeside Renovation & Design handles both exterior and interior remodeling, which makes it a practical option for homeowners planning several connected projects at once.
Its services include siding replacement, window replacement, kitchen remodeling, bathroom remodeling, basement projects, additions and season rooms. That means a homeowner replacing siding and windows while also updating a kitchen or bath does not necessarily need separate contractors for each part of the job.
The exterior work also uses recognizable manufacturer products. Lakeside installs James Hardie siding and Infinity from Marvin windows and holds manufacturer-backed credentials including James Hardie Elite Preferred Contractor status and Infinity from Marvin Gold Partner recognition.
Those credentials are tied directly to the products the company installs rather than being general claims about experience.
Projects are also backed by Lakeside’s Lifetime Workmanship Warranty, giving homeowners long-term coverage on the company’s workmanship rather than only the manufacturer’s product warranty.
For a homeowner planning a project that crosses from the exterior into the interior, Lakeside’s main advantage is coordination. Siding, windows, kitchens, bathrooms and other remodeling work can all be managed through the same company instead of split across several contracts.
Best for Design-Led Whole-Home Remodeling – Hamtil Construction
Hamtil Construction combines residential remodeling with architecture and interior design, allowing homeowners to coordinate design and construction through the same team.
Its services include kitchen remodeling, bathroom remodeling, whole-house renovations, additions, historic renovation, outdoor living spaces, structural work and custom cabinetry.
That design-build approach makes it especially useful for homeowners who want the layout, materials and overall look developed before construction begins rather than treating design as a separate stage handled elsewhere.
Hamtil is a strong fit for larger or more customized remodels where the relationship between rooms, structure and finishes matters as much as the construction itself.
Best for Custom Decks and Exterior Upgrades – STL Design and Build
STL Design and Build offers exterior remodeling services across decks, windows, doors, siding and related projects throughout the St. Louis metro.
Its deck work is a particularly visible part of the business, with custom composite decks, multi-level layouts, replacements and built-in features available for homeowners who want to expand or improve outdoor living space.
The company also installs other exterior components, so it is not limited to decks alone. A homeowner planning a deck alongside new doors, windows or siding may be able to keep those projects with the same contractor.
STL Design and Build offers free estimates and works with low-maintenance composite decking products, making it a strong fit for homeowners whose main priority is an outdoor project but who may also need other exterior upgrades.
Best for In-House Design-Build and New Construction – Agape Construction
Agape Construction handles remodeling, additions, new home construction and maintenance through an in-house design-build team.
Its staff includes architects, interior designers, carpenters and builders, which allows the company to coordinate design and construction internally instead of relying entirely on separate outside teams.
Services include kitchens, bathrooms, basements, additions, custom carpentry and full new-home projects.
That range makes Agape especially useful when a project does not fit neatly into one category. A homeowner considering an addition, major remodel or new construction can work with one company from the early planning stage through the build itself.
Best for Design-Build Remodeling With a Long Warranty – Mosby Building Arts
Mosby Building Arts operates as a design-build remodeling company, meaning the design and construction phases are coordinated under one roof.
Its services include kitchen, bathroom, basement and whole-home remodeling, along with other residential renovation work.
A major differentiator is its 10-Year Workmanship Warranty, which gives homeowners longer-term coverage on the company’s workmanship after the project is complete.
That warranty can be especially useful when comparing firms with similar design-build capabilities because it gives homeowners a clearer idea of how long the contractor stands behind the work.
For someone who wants design, construction and longer-term workmanship coverage handled through the same company, Mosby is a strong option.
Best for Established Local Remodeling Experience – Roeser Home Remodeling
Roeser Home Remodeling is a St. Louis-area remodeling company focused on residential renovation work.
Its services include kitchen remodeling, bathroom remodeling, whole-home updates and other interior projects, with a portfolio that gives homeowners a clear look at completed work before they request an estimate.
That project history makes it useful for homeowners who want to compare finished kitchens, bathrooms and living spaces before deciding whether the company’s style and scope match their own plans.
For someone planning a traditional interior remodel and looking for an established local contractor rather than a highly specialized exterior firm, Roeser is worth considering.
What to Compare Before You Sign a Contract
Scope is the first filter. If a single project touches both the exterior and interior of a house, a contractor that only works on one side may turn a single remodel into multiple hires with separate schedules to coordinate.
Warranty length is another important comparison. A lifetime workmanship warranty and a 10-year workmanship warranty both provide longer-term protection than short coverage periods, but make sure you are comparing workmanship warranties with workmanship warranties rather than mixing them with manufacturer product warranties.
Manufacturer credentials can also be useful because some programs require contractors to meet installation, training, service or performance standards set by the brand. Check what the specific designation actually requires rather than assuming every elite or gold-tier partnership means the same thing.
Before signing anything, ask for warranty terms in writing, confirm exactly which materials and product lines are included in the quote and get a written timeline for each phase of the project.

For exterior work, it is also worth checking independent efficiency standards before accepting broad marketing claims about replacement windows or other building products.
Picking the Right Fit for Your Project
The right contractor depends on how much of the house is actually in play.
Hamtil Construction makes sense for homeowners who want architecture, interior design and construction coordinated through one design-build team. Agape Construction offers a similarly broad approach while also extending into additions and new-home construction.
STL Design and Build is a strong option when the project centers on a deck or other exterior upgrades, while Mosby Building Arts stands out for its design-build model and 10-Year Workmanship Warranty.
Roeser Home Remodeling is better suited to homeowners focused primarily on traditional interior renovation work.
For someone juggling siding, windows and an interior project such as a kitchen or bathroom remodel at the same time, Lakeside Renovation & Design is the clearest fit on this list. Its combination of James Hardie and Infinity from Marvin credentials, interior and exterior remodeling under one roof and a Lifetime Workmanship Warranty makes it especially useful for homeowners who want to manage one coordinated project instead of several separate contractors.
