10 Home Repairs to Leave to the Pros

There are many do-it-yourself home repair projects that can save homeowners money, but some jobs are best left to professional contractors. Attempting complex home repairs without expertise can be dangerous, lead to costly mistakes, and void warranties. Here are 10 home repairs you should always hire a pro for.

Electrical Work

Handling electrical work around your home can risk electrocution, fire, and irreparable damage if wiring is not done properly. Unless you are a licensed electrician, it’s wise to avoid any major electrical project in your house. Here are some electrical repairs to leave to the pros:

Replacing Main Service Panel

The main service panel is the central nervous system of your home’s electrical network. Upgrading it requires permits, adhering to local codes, and precise installation to avoid hazards. Leave it to a seasoned electrician.

Installing New Circuits and Outlets

Running new wiring for additional circuits and outlets requires drilling through framework and knowledge of load calculations. Improper electrical load distribution can overload circuits. Hire an electrician to ensure safety and compliance.

Repairing Appliances and Electronics

Don’t try to repair appliances, large electronics or devices with capacitors like microwaves and old TVs. You risk serious shock without proper training. Call a technician for any major electrical appliance repairs.

Rewiring Old Homes

Old wiring is prone to fraying, corrosion, overloading and other safety risks. Rewiring a whole house is extremely complicated, calling for complete access to wall interiors and specialized skills. Always hire electricians.

Installing Electrical for Additions

If you’re building an addition to your home, the new electrical work involved should meet code and integrate safely with your existing system. Improper wiring can jeopardize insulation and cause fires. Get professional help.

Plumbing Jobs

Like electrical work, plumbing projects require expertise to avoid flooding disasters, gas leaks, and bursting pipes. Don’t take chances on major plumbing repairs – call a licensed pro instead for:

Re-piping Old Homes

If your home has galvanized steel pipes from the 1950s or earlier, they are likely corroded and need replacement to avoid leaks and low water pressure. Re-piping an entire home calls for a professional plumber.

Sewer Line Repairs

Sewer line clogs, leaks and tree root invasions should always be handled by professionals. They have specialized augers, drain snakes and camera equipment along with knowledge of municipal sewer connections.

Gas Line Installations and Repairs

Gas lines carry serious risks if ruptured or installed incorrectly. The consequences of an accident while doing DIY gas line work are too grave. Always hire certified plumbers for any gas line projects.

Main Water Line Replacements

Replacing main water lines and valves is complicated by the need to shut off the municipal connection. Professionals have the tools and skills to minimize disruption to your home during the repair process.

Drain Cleaning in Old Homes

Drain cleaning in a vintage home often requires mechanical augers to clear mineral deposits and grease in old pipes. Hire a pro rather than risk puncturing pipes or scratching porcelain with harsh drain chemicals.

HVAC Repairs

Heating and cooling experts should handle any repairs to furnaces, heat pumps, central air and other HVAC systems. The risks include carbon monoxide poisoning, electrical shocks, and unit damage. HVAC jobs to avoid include:

Diagnosing Faulty Furnaces

If your furnace stops working properly, don’t go poking around its internal components. Only certified HVAC techs can safely inspect controls, fuel supplies, blower motors and heat exchangers for problems.

Fixing Heat Pumps

Faulty heat pumps can leak toxic refrigerants when mishandled. Trained HVAC pros have the tools and knowledge to safely locate and repair leaks, recharge coolant, and fix compressors. Don’t try DIY heat pump repairs.

Replacing Central AC Compressors

Compressors contain refrigerant under high pressure. Attempting a DIY replacement risks releasing these greenhouse gases. Hire certified cooling experts to remove and replace central air compressors.

Installing New HVAC Units

Installing heating and cooling equipment requires following local codes for permits, ventilation, ductwork and electrical hookups. Leave it to the seasoned pros and avoid potential DIY disasters.

Cleaning Ductwork

Improper duct cleaning methods can spread dust and mold spores in your home. HVAC companies use specialized vacuums and equipment to sanitize ducts safely. Trust the experts for this job.

Structural and Masonry Repairs

Any repairs to your home’s structure or masonry require engineering know-how to avoid collapse hazards. Don’t risk DIY disasters – get pros for:

Foundation and Basement Repairs

Cracked foundations need professional-grade epoxy sealing. Bowing walls may require pilings secured deep in the ground. Leave major foundation repairs like these to the structural engineering pros.

Chimney Repointing and Rebuilding

Repointing crumbling chimney mortar takes scaffolding and masonry expertise. Rebuilding damaged chimneys is even more complicated. Bring in experienced masons rather than risk a collapsed chimney.

House Leveling and Stabilization

A house that’s sinking or settle unevenly requires major adjustments to its foundation and structure. This work is best handled by contractors with specialized equipment for lifting and leveling.

Concrete Driveway, Sidewalk and Slab Repairs

Large cracks, crumbling sections, and significant damage to concrete slabs require more than just filling and patching. Hire concrete specialists for proper repairs.

Structural Damage from Pests or Water

Serious pest infestations and water damage can compromise walls, floors, roofs and other structural elements. Get professional assessments rather than cover up symptoms with DIY repairs.

Roofing Repairs

Your roof protects your entire home. Attempting Do-It-Yourself repairs on damaged roofs can have disastrous results. Leave major roofing jobs like these safely in the hands of experienced roofers:

Patching Holes and Leaks

Any significant roof damage beyond a few loose shingles should be remedied by a certified roofer. Improper repairs can lead to worse leaks. Professionals have the right tools.

Re-flashing Problematic Areas

Re-flashing around chimneys, vents and valleys requires roofing mastery to avoid leaks. Don’t risk hacking away at flashing issues yourself — hire a trusted roofer.

Complete Roof Replacements

Taking on a whole roof replacement as a DIY project is asking for trouble. Roofers have the necessary equipment and skills to rip off and install shingles safely and correctly.

Installing Skylights

Cutting holes in your roof requires precision and waterproof installation skills for skylight fixtures. Trying to DIY skylights could result in serious leaks down the road.

Gutter and Downspout Repairs

Seamless gutter repairs, downspout replacement and gutter cleaning are best left to seasoned professionals. Their workmanship and maintenance can help avoid ice dams and water damage.

Garage Door Repairs

Garage doors are under high tension and can cause serious injury if springs or cables snap. Avoid DIY repairs on garage doors beyond basic maintenance. Instead have professionals handle:

Torsion Spring Replacements

Garage door torsion springs can explode if wound incorrectly. Let seasoned garage door technicians replace them to avoid potential harm.

Broken Cable Repairs

Frayed and broken garage door cables can whip around dangerously when they detach. Hire pro technicians to replace damaged cables correctly and safely.

Bent Track Straightening

Bending and warping of garage door tracks can cause rollers to pop out. Attempting to straighten and realign them yourself is difficult and potentially hazardous.

Opener Motor Repairs

If your automatic opener motor is grinding, squeaking or otherwise acting up, play it safe and call a garage door company. They can properly inspect and replace worn opener parts.

Off-Track Door Fixes

Doors that jump the track are extremely heavy to lift and re-align. Let a professional garage door service make tricky off-track repairs for you.


What home repairs should you never do yourself?

You should avoid DIY repairs involving electrical systems, plumbing lines, gas lines, HVAC units, structural elements, masonry, roofing, and garage doors. These require special skills, codes compliance, and equipment to avoid catastrophic mishaps.

When is it OK to do your own home repairs?

Minor repairs like dripping faucets, light fixture replacements, caulking cracks, weatherstripping doors, and touch-up painting are generally safe for DIY. But know your limits and hire pros for more complex repairs.

How can I fix old wiring safely in my home?

You should not attempt any significant electrical repairs on vintage wiring yourself. Hire a licensed electrician to inspect your old wiring and replace components that are overloaded, damaged or not up to current code.

What could go wrong with DIY plumbing repairs?

DIY plumbing mistakes can lead to flooding, mold growth, gas leaks, electrocution, burst pipes, and damage to walls and floors if repairs are done incorrectly. Leave major plumbing repairs to the experts only.

Why is it risky for homeowners to touch HVAC equipment?

HVAC systems contain dangerous electrical components, highly pressurized refrigerants, and risks of fire, explosion, or carbon monoxide leaks if not repaired properly by certified technicians.
