WHAT A "HOME REMODELING" PROJECT ACTUALLY MEANS

Whole-home renovations, additions, basements, mudrooms, laundry rooms, and fireplaces. Five categories. One team. One warranty.

"Home remodeling" covers a wider range of scope than kitchens or bathrooms ever could. The right starting point is figuring out which category your project actually falls into, because the pricing, timeline, and design considerations are different for each. Here is how the five break down.

Whole-Home Renovations

A whole-home renovation touches most or all of the home's interior in a single coordinated project. The most common Lake County whole-home scope we run includes a full kitchen, two bathrooms (primary and one secondary), a powder room, hardwood refinishing across the main floor, paint throughout, lighting upgrades, and electrical or plumbing updates required to support the new layout.

The reason to do a whole-home remodel as one project rather than five sequential projects over a decade is that the trades coordinate once, the permits pull once, the demolition happens once, and the disruption ends in months rather than years. The Cost vs. Value Report consistently shows whole-home renovations recoup 55 to 70 percent at resale.

Investment Range

$150,000 – $700,000+

Most Lake County projects run $150K–$350K. Estate-scale projects in Lake Forest and Lake Bluff routinely exceed $500K.

Typical Timeline

3–5 months on site, plus 4–8 weeks pre-construction

What We Handle

Full project management, all trades, permits, HOA review, warranty

Home addition project in Lake Forest, IL by Century Kitchens & Bath with exterior renovation and expansion

Home Additions and Vertical Expansions

A home addition expands your existing footprint either out (a bump-out, room addition, or larger expansion onto the yard) or up (a second-story addition over an existing single-story home or wing). Build-out additions are typically less expensive per square foot because they require less structural reinforcement. Build-up additions cost more per square foot because they require strengthening the existing foundation, framing, and load paths.

The most common Lake County addition we run is a primary suite addition over the garage or rear of the home. The second most common is a family room or sunroom build-out off the back of the house. We have been working through Lake County addition permitting for decades and know the village setback and lot coverage requirements that shape what is actually buildable on your lot.

Investment Range

$80,000 – $500,000+

Build-out: $150–$350/sq ft. Build-up: $200–$500/sq ft. Primary suite additions: $200K–$450K.

Typical Timeline

3–9 months on site depending on type

What We Handle

Structural engineering, architectural drawings, permits, all trades, finishes

Finished basement in Grayslake, IL by Century Kitchens & Bath with home theater and entertainment area

Finished Basements

A finished basement converts unused below-grade square footage into livable, functional space. Most Lake County homes built after 1990 have unfinished basements at original construction, which means a finished basement adds 800 to 2,000 square feet of usable area at a fraction of the cost-per-square-foot of an addition.

The most common scope includes drywall and ceiling, flooring (luxury vinyl plank, engineered hardwood, or carpet), egress window upgrade if required by code, electrical for lighting and outlets, full HVAC zoning, a wet bar or kitchenette, and either a full or three-quarter bathroom.

Investment Range

$40,000 – $120,000

$50–$100 per square foot in Lake County. Materially less than above-grade addition costs.

Typical Timeline

6–12 weeks on site

What We Handle

Egress windows, framing, insulation, electrical, plumbing, HVAC, flooring, finishes

Custom mudroom built-in with lockers, bench, and storage by Century Kitchens & Bath

Mudrooms and Laundry Rooms

Mudrooms and laundry rooms are the secondary-space projects that disproportionately improve daily life. A well-designed mudroom solves the problem of where coats, boots, backpacks, mail, dog leashes, and seasonal gear actually live—which matters in Lake County where winter brings five months of salt, slush, and snow.

Most Lake County mudroom projects involve carving space out of an oversized garage entry hallway or former pantry, installing custom built-in lockers with bench seating, hooks, cubbies, drawers, and a durable floor. Laundry rooms typically involve relocating from a basement to the main floor, installing front-load washer and dryer with a folding counter, full cabinets, a utility sink, and often a pet wash station.

Investment Range

$15,000 – $80,000

Mudrooms: $15K–$45K. Laundry rooms: $20K–$60K. Combined: $35K–$80K.

Typical Timeline

3–8 weeks on site

What We Handle

Demolition, plumbing, electrical, custom cabinetry, flooring, finishes

Fireplace remodel in Lake County, IL by Century Kitchens & Bath with elegant surround and living room design

Fireplace Remodels

Fireplace remodels are the single most-searched home improvement project in the country relative to project size. The reason is simple: most fireplaces installed between 1985 and 2005 feature brass surrounds, marble facings, and proportions that no longer match current design preferences. Replacing them is one of the higher-impact, lower-cost interior changes available.

The most common Lake County fireplace remodel involves removing the original surround and facing, refacing the firebox with stacked stone, large-format porcelain tile, or shiplap, installing a new mantel sized to current proportions, and updating the surrounding wall treatment.

Investment Range

$8,000 – $40,000

Most projects run $8K–$30K. Larger projects with chimney work or gas conversion can run $40K+.

Typical Timeline

2–6 weeks on site

What We Handle

Demolition, gas line work, facing, mantel, electrical, paint, finishes

WHAT A LAKE COUNTY HOME PROJECT ACTUALLY COSTS

Real pricing, by project type, calibrated to the Lake County market.

Most remodelers refuse to publish pricing for whole-home and addition projects because the variance is so wide that any single number looks misleading. We publish the ranges by scope because every Lake County buyer asks the same question first, and the right answer is a structured range with context, not a sales call.

Pricing by Project Type

  • Whole-home renovations $150K – $700K+
  • Build-out additions $80K – $250K
  • Build-up (second-story) additions $150K – $400K+
  • Primary suite additions $200K – $500K+
  • Finished basements $40K – $120K
  • Mudrooms $15K – $45K
  • Laundry rooms $20K – $60K
  • Fireplace remodels $8K – $40K

Per-Square-Foot Benchmarks

  • Whole-home renovations $100 – $300/sq ft
  • Build-out additions $150 – $350/sq ft
  • Build-up additions $200 – $500/sq ft
  • Finished basements $50 – $100/sq ft

Where the Budget Goes

In a $250,000 whole-home renovation:

  • Kitchen (cabinets, counters, appliances, fixtures) 25–35%
  • Bathrooms (primary + secondary) 20–30%
  • Flooring throughout 8–12%
  • Electrical and lighting 6–10%
  • Plumbing updates 4–8%
  • Paint, trim, doors, hardware 4–8%
  • Permits, dumpsters, project management 5–10%

Why Lake County is Reasonable vs. Chicago

Whole-home and addition projects in the City of Chicago typically run 15 to 25 percent higher than equivalent Lake County projects. The cost premium comes from condo HOA approvals, parking and material delivery logistics, prevailing wage on certain projects, and tighter permit review timelines. Lake County village permitting is generally faster, parking is available, and the median construction year (mid-1990s) means most homes do not carry the same infrastructure-upgrade costs that pre-1950 Chicago homes do.

THE DECISION BEFORE THE PROJECT

Should you renovate, or should you sell and buy something else?

Most Lake County homeowners thinking about a whole-home renovation or significant addition are weighing it against the alternative of selling the current home and buying something larger or newer. The math usually favors renovating, but not for the reasons people expect.

The cost of selling and buying a different home in Lake County typically runs eight to twelve percent of the home's value once you account for agent commissions on the sale (5 to 6 percent), Illinois transfer taxes, Lake County recording fees, moving costs, closing costs on both transactions, and the inevitable cosmetic and functional updates a new home requires within the first two years. On a $700,000 Lake Forest or Libertyville home, that is $56,000 to $84,000 just to change addresses—before you account for any actual improvements to the new property.

That same $56,000 to $84,000 applied to a renovation goes directly into the home you already own. It buys a new kitchen, or a primary suite renovation, or a finished basement. It improves daily life every day. It increases the home's value at resale.

The math changes when:

  • Your current location no longer works (school district, commute, neighborhood)
  • The lot itself is the constraint (no room to expand, drainage problems)
  • The home's bones are fundamentally wrong (single-story when you need two, awkward layout)
  • You have outgrown the home by enough square footage that a meaningful addition is not practical

For most Lake County homeowners we work with, the location is right, the lot is workable, and the bones of the home are sound. The home just needs to function for who they are now. That is what renovation solves.

If you are at the point of running this math yourself, the free Century consultation is the right next step. We will measure your home, talk through your goals, and tell you honestly whether the renovation makes sense or whether the math on this specific home favors selling. We have turned away projects where renovation was not the right call. The conversation is free.

WHERE WE BUILD

Whole-home renovations and additions across Lake County, Illinois.

Century's showroom is in Third Lake, in the 60030 ZIP code that also serves Grayslake. We design and build whole-home renovations, additions, basements, and other large-scope projects across all of Lake County, with most projects within a thirty-minute drive of the showroom.

HOW A LARGE-SCOPE PROJECT WORKS WITH CENTURY

The same five-step process that runs kitchens and baths, scaled up for whole-home and additions.

1

Free Showroom or In-Home Consultation

We come to your home. For projects involving structural changes or additions, we walk the existing space, measure carefully, and discuss what is buildable on your lot given setback requirements, lot coverage rules, and the home's existing infrastructure. We talk through your goals, timeline, and budget. No deposit, no pressure, no obligation.

2

Design and 3D Rendering

Your designer develops the floor plan, elevation drawings, and 3D renderings of the finished project at no charge. For additions or structural projects, we coordinate with structural engineers as needed. For HOA-governed properties, we prepare the architectural submission package.

3

Selections in Our Showroom

You pick every finish, fixture, surface, and material across every room in the project. For whole-home renovations, this typically runs across several appointments to keep selections aligned across rooms and consistent with the overall design direction.

4

Menu-Style Itemized Estimate

Every line itemized across every scope element. Kitchen, bathrooms, flooring, paint, electrical, plumbing, structural work, foundation, roof, exterior, permits, dumpsters, and project management. Nothing buried. You sign once.

5

Build, Inspect, Warranty

Our in-house licensed crews execute on the schedule we promised. For projects running three to six months, we provide weekly progress updates from your designated project manager. We pull every permit and meet every inspector. When the project is complete, your written limited lifetime warranty goes in the file.
