12 Hidden Renovation Costs That Can Sink Your Budget

You knew this renovation would be expensive. But you were smart. You accounted for everything in your budget.

Or, you thought you did.

Two weeks into your kitchen makeover, your wallet is weeping. Your Goldendoodle Sadie freaked out over the noise and needed doggie daycare. Your lawn is a disaster zone. And who knew one family could spend so much money eating out?

Surprises happen. Shelling out cash on unexpected renovation costs isnt completely avoidable -- but there are plenty of hidden renovation costs you can prepare for. Here are some of the surprising things that can set your wallet on fire during your next big project.

#1 Extra Muscle: 500

Even if youre just clearing out the renovation space by moving boxes downstairs, you still might find yourself in need of a few strong hands.

For the longest time, we thought we could clear out the space ourselves, says Summer Sterling, who renovated her homes entire top floor, including gutting the kitchen, updating two bathrooms, and vaulting a ceiling. She and her husband lived in the basement during the remodel. Then we realized we have this gigantic furniture.

The Sterlings moved as much as they could beforehand, but the movers still cost about 500.

#2 Anxious Pups: 125 Per Week

Some pets have nerves of steel. Others cower at any unexpected noise or strangers. And construction zones are full of noisy strangers: dropping wrenches, hammering, or stomping through your home in metal-toed boots.

Monitor your dog to see how he handles the stress. If the answer is not well, prepare for a brief boarding -- although you might find a mid-day dog walker or a short stay with Nana is soothing enough (and far less expensive).

Sterling and her husband adopted a new dog shortly before the remodel. It was tough on our little guy, she says. He likes to sleep all the time.

Their two pups doubled their time in doggie daycare -- stressful for the dogs and the budget. But planning your work during your sitters down season can save you some cash.

#3 Dinners Out: 80 Per Week

Cooking without a kitchen challenges the best chefs -- theres a reason its a stalwart Top Chef challenge. Even if your kitchen remains intact during the reno, putting together a meal in a home filled with dust is no fun at all.

Sterling and her husband ate out or ordered take-out at least three or four times a week, she says.

Instead of single-handedly funding your favorite restaurants expansion, she recommends storing pre-prepped, microwaveable meals in a chest freezer. Or setting up a makeshift kitchen.

#4 Dumpster Fees: 400

Construction junk has to go somewhere. If youre DIYing the remodel, dumpster fees might come as a surprise.

Expect to spend about 400 on your trash-mobile, but contractors can provide localized, ballpark dumpster estimates.

Once its in your driveway, save some extra cash by using the dumpster to ditch unwanted stuff accumulating around your house. Tired of those nasty old blinds? Say adieu, without paying extra disposal fees. Just leave room for the construction junk.

#5 Hotel Stays: 500

Youre determined to live at home during the reno, but if a contractor accidentally smashes through your bedroom wall or the noise gets too unbearable, you might find yourself packing up for a short stay in a nearby hotel.

You dont need to book your staycation beforehand, but budgeting enough cash for a few days away will make the decision to abandon ship a bit less stressful. Or hole up with some friends -- just make sure to bring wine and cover dinner as payment.

#6 Childcare: 175 Per Week

Checking your calendar, you realize demo day coincides with school inservice. You cant have the adorable little rascals stomping through the dust -- so off to the sitters they go. Great. Another 100 down the drain.

Keep a close eye on the calendar and pre-arrange playdates for their days off to keep your wallet in check. Or bring over Aunt Margie to keep the kids corralled (and entertained) in a spare bedroom.

#7 Labor Costs: 50 Per Hour

Delays, schedule changes, and unexpected surprises dont just add time to the renovation -- they mean paying more to the workers.

Our labor costs wound up being much higher, says Janet Heller, whose sink broke during a bathroom renovation -- requiring multiple trips and two times the work from contractors and laborers.

Know each contractors hourly cost so when disaster strikes, you can budget appropriately.

#8 Professional Cleaning: 150

Your new kitchen features sparkling, brand-new marble and stunning oak cabinetry -- but you cant ignore the fine layer of sawdust covering everything.

Construction dust is everywhere, Sterling says. Allocate a few days for a top-to-bottom clean. Scrubbing everything yourself can save you some much-needed cash.

But if the mess is too daunting, consider hiring a service as a post-renovation treat. Even if theyre just handling the hard-to-reach spots, a little help will be more than welcome. Now all you have to do is go home, kick back, and heat up your very last frozen dinner.

#9 Office Space: 195 Per Month

Telecommuters have their own renovation challenges. How can you take a phone call with clients when a drill is whirring overhead?

I work from home, but am unable to function with so much construction noise above me, Sterling says. Theres no privacy whatsoever. But privacy doesnt come cheap: A flexible desk at a co-working space can cost 195 per month -- and more if you need a closed door.

Sterling leased a temporary office twice per week during the renovation and lowered costs by working out of coffee shops or a library as often as possible.

#10 Higher Utility Bills: 15%-20% Extra

Doors opening. Fans whirring. So many power tools. Is there anything in construction that doesnt suck up energy?

Were living in a much smaller space, but the efficiency is terrible, says Sterling, who spent about 15% to 20% more on electricity during the renovation. The bloody contractors leave the windows open all the time.

Dont feel bad if youre a bit of a nag. Unless the breeze is necessary (drying paint and new hardwood floors require ventilation), pop upstairs every evening to close the windows.

#11 Lawn Landscaping: 1,500

Did they really need to put their equipment on your beautiful Kentucky bluegrass? For some reason, renovating the interior can mean your lawn takes a beating that only a professional landscaper can repair.

Ask contractors beforehand if they plan on using your yard for staging, and place down tarps to protect the foliage. Or find alternative spots, like the attached garage or gravel driveway.

#12 Permits: 1,000

Before the first sledgehammer swings, sit down with your contractor (or city building department) for a detailed discussion of exactly what permits you need.

Usually a contractor will include plans and permits, Rinek says.

But make sure you know early on if they dont, otherwise youre in for a surprise. Sterling says she paid more than 1,800 in permit fees -- causing major sticker shock, if youre not expecting the bill.
