Remodeling 1970s Bathrooms in Lakewood, CO: Hidden Costs & Challenges
Lakewood is defined by its beautiful, established neighborhoods. Homes in Belmar, Eiber, Alameda, and Green Mountain boast incredible character, large lots, and solid bones. However, if you own a home built between 1960 and 1985, you also have something less desirable: an aging, original bathroom.
Pink square tiles, dropped luminous ceilings, carpeted floors (yes, really), and cramped layouts are the hallmarks of this era. But the real challenges of remodeling an older Lakewood bathroom aren't the ugly aesthetics—it's what is hiding behind the walls.
After remodeling hundreds of older homes across Jefferson County, we've seen it all. If you are planning to update a historic or mid-century bathroom, here are the hidden costs and structural challenges you need to budget for.
The Galvanized Pipe Problem
If your home was built before the late 1970s, there is a high probability it was plumbed with galvanized steel pipes. Over decades, these pipes corrode and rust from the inside out. The result? Rusty brown water when you turn on the faucet and terrible water pressure.
The Hidden Cost
When we open the walls for a remodel, we cannot attach a brand new $500 shower valve to a crumbling 50-year-old pipe. We have to replace the branch lines with modern PEX or copper. Replacing old plumbing in the bathroom walls typically adds $1,000 to $2,500 to the overall remodel cost.
Asbestos and Lead Paint
Colorado state law takes asbestos seriously. If your home was built before 1985, a licensed inspector must test the materials before any significant demolition begins. In 1970s bathrooms, asbestos is commonly found in:
- Vinyl floor tiles and the black mastic adhesive underneath them.
- Drywall joint compound (mud).
- Textured "popcorn" ceilings.
The Hidden Cost: Testing costs about $200–$600. If the results are positive, a certified abatement team must safely remove the materials before the remodelers can start. Abatement in a small bathroom usually adds $1,500 to $4,000 to the budget and adds about a week to the timeline.
Water Damage and Rotted Subfloors
Bathrooms are wet zones. Decades of micro-leaks around the tub flange, a poorly sealed toilet wax ring, or failing grout inevitably leads to water reaching the wood structure of your home.
It is extremely common for us to pull up the 1970s linoleum to find that the plywood subfloor around the toilet is soft and rotted.
The Hidden Cost: We have to cut out the rotted wood and replace it to ensure a solid foundation for your new tile floor. Depending on the extent of the rot, subfloor repair adds $500 to $1,500. If the floor joists are damaged, costs can climb higher.
Electrical Woes: No GFCIs or Exhaust Fans
Electrical codes in the 1960s were vastly different than today. Two common issues we find in older Lakewood bathrooms:
- No GFCI Outlets: Ground Fault Circuit Interrupters (the outlets with the "reset" buttons) are legally required near water sources to prevent electrocution. Older homes rarely have them.
- No Exhaust Fan (Or Venting into the Attic): Older building codes allowed bathrooms to have no exhaust fan if they had a window. If they did have a fan, it was often vented directly into the attic, which pumps moist air into the roof space, causing mold.
The Hidden Cost: Upgrading the electrical panel (if necessary), adding GFCI circuits, and properly venting a new exhaust fan through the roof adds $500 to $1,500 to the electrical budget.
Contractor Tip: Budgeting for the Unknown
When remodeling a home older than 40 years, a reputable contractor will recommend a 15% to 20% contingency budget. This is money set aside specifically for things we can't see until we open the walls. If we don't need it, you don't spend it. But having it ready prevents mid-project stress.
Is It Worth It? (The Resale Reality)
Reading about hidden costs can be daunting. But here is the reality: updating a 1970s bathroom yields some of the highest Return on Investment (ROI) of any home improvement project.
Buyers in the Lakewood real estate market are actively looking for the charm of an older home without the maintenance nightmares. When you tear out the galvanized pipes, remove the asbestos, and install a beautiful, modern tile shower, you eliminate the biggest fears a buyer has. A remodeled master bath in an older Lakewood home can easily add $20,000 to $30,000 to the home's resale value.
Expertise Matters in Older Homes
Don't trust your historic Lakewood home to a franchise that just glues plastic over old problems. We do full structural guts, fix the plumbing, and build it right.
Frequently Asked Questions
Do I need to replace galvanized pipes during a bathroom remodel?
Yes, absolutely. If your Lakewood home still has original galvanized steel pipes from the 1960s or 70s, they are likely corroding from the inside out, causing low water pressure and rusty water. A bathroom remodel is the perfect time to replace them with modern PEX or copper while the walls are open.
How much does asbestos testing cost in Lakewood?
Professional asbestos testing in Jefferson County typically costs between $200 and $600. If your home was built before 1985, state law requires testing before significant demolition. If asbestos is found in the drywall mud or floor tiles, abatement adds $1,500 to $5,000 to the project.
Why do older bathrooms have such low water pressure?
In older Lakewood homes, low water pressure is almost always caused by mineral buildup and corrosion inside old galvanized steel pipes. The pipe's interior diameter shrinks over decades, restricting flow. Replacing the pipes during a remodel solves the issue permanently.
Can I expand my small 1970s bathroom?
Yes, but it requires structural work. Older homes often have very small, compartmentalized bathrooms. We can expand the space by taking square footage from an adjacent closet or bedroom, though this adds significant cost due to moving walls, electrical, and plumbing.
What is a mud job shower pan?
Many older homes have a 'mud job' shower pan, which is a thick layer of concrete poured over a lead or copper liner. These are extremely heavy and difficult to demolish. We replace them with modern, lightweight waterproof systems like Schluter-Kerdi that are far more reliable.
