Rewiring Boulder houses is slower, fussier work than most of the metro, and we mean that as a compliment to the houses. Mapleton Hill, Whittier, and Goss-Grove still have homes from the 1890s through the 1920s with plaster walls, balloon framing, and wiring that has been patched by four generations of owners. Modelco Electric Corp has been doing this work since 1993. We come up 36 from Thornton, and yes, we still look at the Flatirons from the Davidson Mesa overlook every single time.
This is where knob and tube actually lives on the Front Range. Not every old Boulder house still has it energized, but plenty do, usually in the original rooms with newer cable spliced in wherever someone added a bathroom or a kitchen. Insulation blown over it in the attic makes it worse when rewiring Boulder attics gets put off, because those runs were designed to shed heat into open air. Knob and tube wiring replacement here starts with finding every live run, which takes more than a quick look in one junction box. Our rewiring service covers the full process, from tracing to final inspection.
Drywall cuts clean and patches in an afternoon. Plaster cracks if you look at it wrong. On a Whittier or Mapleton Hill house we route as much as possible through the attic, the basement, and behind baseboards, door casings, and crown molding. Where a wall has to open, the hole is small and planned. Rewiring Boulder homes this way takes longer on the front end and saves you a lot of plaster repair at the back end.
Some of these homes sit in historic districts. Interior wiring is not the concern there. Moving a meter or adding a service mast on the street side can be, so we keep exterior changes to the side or rear wherever we can.
Landlords on University Hill call us for a specific reason: the rental license inspection. Old student houses tend to fail on the same items. Ungrounded outlets, overloaded bedroom circuits, a basement room fed by an extension cord, a fuse panel nobody wants to talk about. We do residential rewiring on these between leases, in the summer window when the house is empty, and a pre-inspection electrical safety check tells you exactly what will fail before the city inspector does. One bad circuit gets a targeted repair, not a sales pitch.
Boulder is going all-electric faster than anywhere else on our route. Heat pumps, induction ranges, heat pump water heaters, and an EV in the garage. Each one wants its own 240-volt circuit, and an older house rarely has the capacity or the breaker space. Electrification is a good moment for whole home rewiring if the old wiring is already on its way out, and a bad moment to bolt new loads onto circuits from 1948. A larger service panel usually comes first. While the panel is open, add whole-home surge protection to cover all that new equipment.
Matt Moody owns the company and has more than twenty years in the trade. We are licensed and insured, five people total, and the electrician who walks your house is the one who does the work. Boulder owners tend to have done their research before they call, and they ask good questions about grounding, plaster, and permits. We answer them straight. When someone in Boulder searches house rewiring near me, a crew with thirty-plus years on old houses is the useful result.
Beyond the city we cover Gunbarrel, Niwot, Louisville, Lafayette, Superior, and Longmont. Down the turnpike, the 1960s bi-levels in Northglenn are an easier job than any Mapleton Hill Victorian, and we handle Northglenn rewiring too. If you are looking for house rewiring near me anywhere between Boulder and the Thornton shop, it is the same crew. Our electrical rewiring services page walks through a typical job day by day.
Get it out of service. Most carriers want it gone or want a written plan from a licensed electrician before they renew. We find every live knob and tube run, replace it with grounded copper, and give you the permit and inspection paperwork to send the insurer. In a lot of Boulder houses the old runs are concentrated in the original rooms, so the job is smaller than the letter makes it sound.
No. Plaster and lath is harder to fish through than drywall, so we do more of the work from the attic, the basement, and behind baseboards and trim. Where we do have to open the wall, the holes are small and planned. We mark every one on a walkthrough before work starts, so you know what patching to expect in each room.
Interior wiring does not. Changes you can see from outside can, such as a new meter location, a service mast on the front of the house, or new exterior fixtures. If the panel or service is moving as part of the project, we plan it for a side or rear wall and check with the city about review before anything is ordered.
Yes. Boulder rental licensing requires a safety inspection, and old wiring in student rentals is one of the usual problem spots: ungrounded outlets, overloaded circuits, extension cords running to a basement bedroom. We fix what the inspector will look for and schedule the work between leases when the house is empty, which is the fastest and cheapest window.
Often you need new circuits more than a full rewire, plus a panel with room for them. Electrifying a Boulder house adds big 240-volt loads, and an older 100-amp service may not carry them alongside a car charger. We run the load calculation, tell you which existing circuits are worth keeping, and plan the new ones so you do not open the same walls twice.
Plan on one to two weeks for a typical Whittier or Mapleton Hill house, depending on size, plaster, and how much of the basement is finished. Smaller post-war houses in north Boulder go faster. We restore power to the rooms you are using at the end of each day.
Inside city limits it is the City of Boulder. Parts of Gunbarrel and the foothills west of town are unincorporated Boulder County, which runs its own permit and inspection process. We confirm which applies from your address and pull the right one either way.
It depends on square footage, plaster versus drywall, attic and basement access, the number of circuits the house needs, and whether the panel stays. We do not price it over the phone. After a walkthrough you get one written quote with labor, materials, permit, inspection, and the patching plan spelled out.
Tell us the year the house was built, whether you have seen knob and tube, and what is driving the project: an insurance letter, a rental inspection, a heat pump, or flickering lights in the back bedroom. Then set up a visit. We will trace what is in the walls, check the panel, and put the plan for rewiring Boulder homes like yours in writing, permit and inspection included. If the panel needs replacing we price it as a separate line.
