Biggest Mistakes in Renovation

Not having a proper project plan or a scope of work can cause major delays and change
orders. A detailed scope of work prevents us from making costly mistakes during renovation.
When we outline every step before we start, we can choose the contractor based on exactly
what we need and the contractors will know exactly what to expect.
Key planning elements include:
- Detailed budget breakdown
- Material specifications
- Project timeline with milestones
- Permit requirements
- Temporary living arrangements

Working with pros who understand your goals and can give you advice based on your
needs, can help you develop your project plan to the best way possible. Clear
communication with contractors should start from our first meeting. We need to share
our vision, budget limits, and must-have features upfront.
Good professionals ask detailed questions about our lifestyle and preferences. They
should understand how we use each space before suggesting changes.

Renovation cost is usually underestimated by homeowners/ developers. It is suggested by professionals,
to set aside 10-20% of the whole project’s budget for unexpected costs. Other than permits, structural
issues behind the walls or material price changes, Kitchen and bathroom remodels have the most
hidden costs. Water damage, electrical upgrades, and plumbing relocations can be more expensive than
expected.
Another common unexpected cost in remodeling projects is design changes made in the middle of the
project. This can increase costs significantly and that is another reason that early consultation help you
understand the problem you want to resolve by renovation, to not simply cover it up, or spend too
much for it.
Over budgeting a renovation on the other hand, can be a big mistake. 30% rule, is a budgeting guideline
and suggests you should generally avoid spending more than about 30% of your property’s current value
on a renovation. For example, if your home is valued at $300,000, according to the 30% rule, you should
aim to keep your renovation costs below $90,000. This includes all aspects of the renovation—labor
costs, materials, permits, and any additional expenses that may arise during the project. However,

remember that 30% rule is not the law! It is a recommendation based on prior experiences. It can be
exceeded in many situations for instance if you plan to live in the place long-term, or your house is in a
high value neighborhood.

Your location and the type of work you plan to do will determine which permits are required. local
authorities may need to approve any big changes, electrical work, or plumbing upgrades. In some cases,
approval from your homeowner’s association may also be necessary. Without these in place, you could
run into issues during a home inspection when it comes time to sell.

A lower estimate might seem appealing at first, but if the contractor lacks proper insurance, bonding,
licensing, or certifications, it can lead to bigger expenses down the line. In many cases, choosing a
qualified and fully verified professional upfront is the more cost-effective decision. Sometimes bids that
win on price omit necessary prep work, water proofing, ventilation, and/or proper finishing details.
Bringing in experienced, qualified contractors can make a big difference in how smoothly your
renovation goes—especially when dealing with older homes. Skilled professionals understand proper
installation methods for fixtures and appliances and know what it takes to deliver accurate, high-quality
work. Also don’t hesitate to ask about their experience with projects similar to yours, it’s important to
find someone whose background aligns with your needs.

Many homeowners begin projects without a detailed agreement covering the scope of work, materials,
schedule, and payment terms. This often results in confusion, delays, or even disputes. It’s important to
have a clear, thorough contract in place and to establish a timeline with defined milestones to track
progress.
Every stage of a renovation requires thoughtful scheduling between you and your contractor. Planning
ahead, ordering materials early, and setting flexible deadlines can help you avoid last-minute stress. It’s
also wise to include extra time in your schedule to account for potential delays, which are common in
most projects. This buffer can make the entire process feel much less overwhelming. With realistic
timing, your project is far more likely to stay on track and run with fewer surprises.

Many minor misunderstandings grow into costly re-dos. No written documentation, no decisions made
in writing, and no weekly meetings/check-ins, can extremely increase these costs. Communicate your
concerns clearly and don’t hesitate to ask questions about decisions like lighting, appliances, or design

details. Regular check-ins can help you stay updated on progress and keep everyone on the same page.
Forgetting about upkeep after the remodel

Rushing into next steps in a renovation project can create unnecessary pressure and lead to mistakes
that require rework. For example, when materials or fixtures arrive before they’re needed, they often
have to be stored elsewhere, which can result in extra handling or even damage. Items that are out of
sight can easily be overlooked, and installing elements too early—like flooring—can expose them to
scratches, paint spills, or other damage during later stages of the project.

It may seem straightforward, but many homeowners overlook important documents or skip detailed
discussions with their architect or contractor simply because they don’t realize how much impact these
steps have. For instance, failing to review an electrical plan—like deciding where outlets and switches
should go—can lead to regrets later, especially if you assume changes will be easy to make after
installation.
Similarly, relying only on an architect’s past work without asking for project-specific visuals can be risky.
Requesting 3D models or renderings of your actual space helps you better understand the design and
avoid surprises. Taking the time to ask for these details upfront can save you from costly adjustments
and dissatisfaction later on.
