5 Budgeting Challenges for a Historic Renovations in Kensington Connecticut You Need to Know

Renovating a historic home is one of the most rewarding projects a homeowner can take on, but it's also one of the hardest to budget accurately. Older homes weren't built to modern codes, and a lot of what needs attention isn't visible until walls are opened. If you're planning a renovation on a historic or older Connecticut home, here are six budgeting challenges worth planning for before you get started.

At MS Contracting & Electric, we work on a lot of older homes across Connecticut, and these are the surprises that come up again and again.

1. Outdated Electrical Systems

Many historic homes still have knob-and-tube wiring, undersized panels, or wiring that simply wasn't built for modern electrical loads. Bringing a system up to code often means a full rewire, not just a panel swap, which is a bigger line item than most homeowners expect going in.

2. Hidden Structural Issues

Settling foundations, rot, and framing that's shifted over decades are common in older homes and usually aren't visible until walls, floors, or ceilings are opened up. It's worth budgeting a contingency specifically for structural surprises rather than assuming the framing is in good shape.

3. Permitting and Historic District Requirements

If a home is in a designated historic district, changes to the exterior, windows, or certain structural elements may need approval beyond a standard building permit. That review process can affect both cost and timeline, so it's worth checking early whether your home falls under any local historic guidelines through your town's building department.

4. Custom or Hard-to-Match Materials

Matching original trim, siding, flooring, or windows often means custom millwork instead of off-the-shelf materials. Custom work costs more and takes longer to source, especially for anything meant to match a specific architectural period.

5. Plumbing That Doesn't Meet Current Code

Old cast iron or galvanized pipes are common in historic homes and are often at or past the end of their usable life. Replacing them, especially if they run through finished walls or floors, adds cost that isn't always obvious from a simple walkthrough.

How to Budget for These Challenges

The honest answer is a bigger contingency than you'd build into a newer home renovation. Where a standard remodel might budget 10 to 15 percent for unknowns, historic renovations often warrant closer to 20 to 25 percent, simply because so much of the home's condition isn't visible until work begins.

FAQs

Why do historic home renovations cost more than newer homes? 

Older homes often need updates to bring electrical, plumbing, and structural elements up to current code, and issues like lead paint or hidden damage aren't visible until work starts.

Do I need special permits for a historic home renovation? 

It depends on whether the home is in a designated historic district. Exterior changes and some structural work may require additional review beyond a standard permit.

How much contingency should I budget for a historic renovation? 

Many contractors recommend 20 to 25 percent above the base estimate, compared to 10 to 15 percent for a typical remodel, to account for hidden issues.

Is it more expensive to rewire an old house than a newer one? 

Usually, yes. Older wiring like knob-and-tube often requires a full rewire rather than a partial upgrade, since it wasn't built to handle modern electrical loads.

Can I keep original materials during a renovation? In many cases, yes, especially trim, flooring, and windows, though damaged or unsafe materials may need to be replaced or carefully matched with custom work.
