Things You Need To Check Before Moving To an Old House


Exploring old houses is like walking into a different era, where every squeaky step and chipped paint has its own tale. These buildings are more than just places to live; they’re pieces of history with unique stories and mysteries. But with the beauty of old architecture comes a set of challenges tucked away behind those classic facades and old-timey doors.

Before you decide to make one of these historical gems your own, there’s a lot to consider. It goes beyond the appeal of rustic wood and colorful stained glass; it’s about digging deeper to understand what makes the house truly special.

This guide will walk you through the key things you need to think about before taking the plunge into owning an old house, helping you see beyond the surface charm to find a home that’s right for you.

Structural Integrity

The structural integrity of an old house is paramount to its safety and longevity. Issues like foundation cracks, sagging floors, and deteriorating roofs can signal significant problems that might be costly to repair and dangerous. A comprehensive inspection by a qualified structural engineer can uncover hidden defects and provide an assessment of any necessary repairs. This step is crucial to avoid future surprises and ensure the house stands solid for years to come.

Asbestos and Other Hazardous Materials

A major issue with older homes is the presence of asbestos and other hazardous substances. Asbestos, favored for its fire-resistant qualities, was a common building material up until the late 20th century. The danger lies in its fibers, which can lead to serious health problems, including mesothelioma—a severe cancer that targets the lung lining. Resources like offer crucial insights into the dangers of asbestos exposure and provide advice on managing it safely. To prevent the risk of releasing dangerous fibers into the air, especially during renovations, it’s vital to have professionals carry out an asbestos inspection before settling into an older home.

Electrical System and Plumbing

Older homes often have outdated electrical systems and plumbing that may not meet current safety standards. Knob-and-tube wiring, still present in some houses built before the 1950s, poses a fire hazard, while old plumbing pipes can lead to leaks or water quality issues. Inspecting these systems thoroughly is essential to identify any updates needed to ensure they are safe, efficient, and capable of handling modern demands. Upgrading electrical systems and plumbing can be a significant expense, so factoring these costs into your budget is vital.

Heating, Ventilation, and Air Conditioning (HVAC)

The condition of the HVAC system in an old house can greatly affect your comfort and energy bills. Older systems may be less efficient than newer models, leading to higher heating and cooling costs. They can also struggle to maintain consistent temperatures throughout the house. Checking the age and condition of the HVAC system and considering the potential need for replacement or upgrades is important for ensuring a comfortable living environment and managing long-term costs.

Insulation and Energy Efficiency

Many old homes lack adequate insulation, leading to energy inefficiency and uncomfortable living conditions. Poor insulation in walls, attics, and basements can result in significant heat loss during winter and make cooling more challenging in summer. Evaluating the home’s insulation and overall energy efficiency is crucial. In some cases, adding insulation or making other energy-efficient upgrades can improve comfort and reduce utility expenses, making it a worthwhile investment for the future.

Lead Paint

Homes built before 1978 are likely to contain lead-based paint, which poses serious health risks, especially to children and pregnant women. Lead exposure can lead to neurological damage and developmental delays, among other health issues. Testing for lead paint is a critical step in the home inspection process. If lead paint is present, professional remediation techniques, such as encapsulation or removal, may be necessary to make the home safe for its inhabitants. Understanding the scope and cost of these measures is essential for any potential homeowner.

Pest and Rodent Infestations

Due to structural gaps and aging materials, older homes may also be more susceptible to pest and rodent infestations. Termites, carpenter ants, rats, and mice can cause significant damage to the wood and wiring, posing both a financial and health risk. A specialized pest inspection can reveal the extent of an infestation and the steps needed for eradication and prevention. Addressing these issues before moving in is crucial to prevent further damage and ensure a clean, safe living environment.

Water Damage and Mold

Water damage and mold are common in older homes, resulting from leaks, poor drainage, or condensation issues. Mold can lead to serious health problems, including respiratory issues and allergic reactions. Inspecting for signs of water damage and mold—not just on the surface but also in hidden areas like basements, attics, and behind walls—is necessary. Professional mold remediation can be costly but is imperative for the health and safety of the home’s occupants.

Local Building Codes and Regulations

Compliance with local building codes and regulations is another critical factor to consider. Older homes may not meet current standards for safety and efficiency, and bringing them up to code can be a significant undertaking. It’s important to research local regulations and possibly consult with a contractor or architect to understand what changes need to be made. This understanding can impact your budget and timeline for moving in and should be considered in the early stages of your home-buying decision process.

Historic Preservation Restrictions

If the old house is located in a historic district or designated as a historic property, there may be restrictions on the types of changes you can make. These restrictions can affect everything from exterior paint colors to structural modifications. Contacting the local historic preservation office or society can clarify these restrictions and help you understand how they might impact your renovation plans and overall enjoyment of the property.


Moving into an old house offers the unique opportunity to inhabit a piece of history, but it also requires careful consideration of several critical factors to ensure the property is safe, livable, and in line with your expectations. From the health risks associated with lead paint and asbestos to the practical concerns of pest infestations, water damage, and compliance with building codes and historic preservation restrictions, it’s essential to conduct thorough inspections and research before committing.

Understanding these aspects and preparing for the potential work and costs involved can help you make an informed decision, ensuring that your old house becomes a cherished home. Embracing the journey with patience and diligence can transform challenges into rewarding investments, making your dream of owning an old house a reality filled with character, charm, and comfort.
