My house was built in 1925 and is a 1-1/2 story residence. I've always had problems cooling the upstairs, even with central air conditioning. In the summer, it is unbearably hot upstairs, even with the a/c cranked up. In the winter, it is coolish upstairs, but certainly livable (heat rises). My house has old style vents on the first floor - large square supply vents (5) and two in-floor rectangular return vents. Upstairs, there are only two supply vents and the return air vent is really the stairway down to the first floor. The Aeroseal product addresses the excessive duct leakage that exists in any home. Even if you manually seal by tape the ductwork in your house, there is still quite a bit of leakage. I did a lot of research before getting this product installed, and case studies show that this product consistently reduces leakage by more than 90%. Our heating and cooling appliances are now pretty energy efficient, but the duct work in a building is still a source of a lot of heat/cooling loss. According to the manufacturer, here's some of the technology: 1. Research for Aeroseal was partially funded the US Dept of Energy 2. Aeroseal is the only duct sealant technology that is applied from the inside of the duct system. It is delivered as a non-toxic aerosol mist that seeks out and plugs leaks. 3. Aeroseal has proven to be 95% effective at sealing air duct leaks. 4. The Dept of Energy proclaimed aeroseal technology to be one of the top 23 most important energy conservation technologys for consumer sto come out since the dept was first established. 5. The product was developed at Lawrence Berkeley National Laboratory in 1994. 6. Aeroseal has won several prestigious awards, including DOE energy 100 Award, Popular Science -Best of What's New, This Old House - new technologies and 2012 EBie award for use on an existing building retrofit project. I recommend going to the manufacturer website to get more information and view a video of how the installation works. Also, check out the This Old House segment online when they featured this product. When I looked for an Aeroseal service provider in the Twin Cities, Northern One Hour Heating & Air Conditioning was the only provider. In fact, I contacted them only about a month after they started providing this product. They had a service technician trained by the manufacturer to install the product, and they had done several new house installations. Mine would be the first "old house" in which they would install the product. (Therefore I did get a very nice price discount.) The company sent two technicians to install the product. They arrived on time. The set-up definitely takes the most time- it took a couple hours for my house. They have to seal all the vents tightly and tape up larger gaps in the duct work before starting the actual sealing process. They do a computer analysis before and after the sealing process so that actual results can be measured. (One of the technicians still said that my old house duct work was tighter than new house construction to begin with.) While installing, there was a fine mist that developed in the air. The company has a fan/vacuum that collects a lot of it. Also, they opened a lot of windows to help dissipate the mist. They provided masks for us to wear - I actually didn't wear it though. Breathing the substance created a little stickiness in my nose, but eventually it went away. The mist dissipates quickly. It is supposed to be non-toxic. The sealing itself took about 15 minutes for the supply side, and 25 minutes for the return side. The supply/return sealing can be performed dually, but this company does each side separately. My results are as follows: Supply ducts - original leakage was equivalent to a 25 square inch hole. After finishing the Aeroseal, leakage was equivalent to a 1 square inch hole, corresponding to a 95% reduction in duct leakage. Return ducts - original leakage was equivalent to a 43 square inch hole. After finishing the Aeroseal, leakage was equivalent to a 5 square inch hole, corresponding to a 89% reduction in duct leakage. Clean-up was quick. They left my house in tip-top shape. I also received a printed Certificate of Completion that outlines the overall sealing results for both the supply and return sides. I am really pleased with the results, and I can say that the product really works. For the first time, I can cool my upstairs without the use of a window air conditioner upstairs. I can cool it to be about 2 degrees difference from the first floor. I set the thermostat to 74 degrees and close all the supply vents on the first floor except one. Upstairs, the temperature is about 76 degrees. I am anxious to see what happens in the winter, although summer cooling was the more problematic issue for me. I can also report a HUGE reduction of the dust in my house. Before, I used to see the dust pile up just a few days after dusting. Now, it is over 2 weeks since my last dusting and I still don't see the dust pile up on the furniture or window sills. I highly recommend this product to any homeowner. It saves energy, is good for the environment, and most importantly - improves indoor comfort and reduces dust in your own home. I commend Northern One Hour Heating & Air Conditioning for being the first service provider in the Twin Cities for this product. I hope they get a lot of business installing this product. They did a great job and I couldn't be happier.

Dakota was higher-priced, but offered more ideas and spent more time with me discussing the design - which is what I wanted and needed. Dakota came in after I had a new retaining wall installed by another vendor. Joe, the Dakota salesman, was in touch with the wall vendor ahead of time in case they had to think about this fence project while installing the retaining wall. In the sales process, Joe was very polite and helpful, punctual and worked around my schedule nicely. He provided me with a quote and blueprint of where the fence would go in my yard within 24 hours of my meeting with him. I wanted the fence to totally enclose my backyard to accommodate my dogs. Joe suggested a cedar wood picket-type fence. I liked the pictures he showed me and opted for that. We spent some time discussing gates as well. Chain link was used in one small corner of the yard that would join up with my neighbor's fence. Since I had my fence join up to my neighbor's property, I had to get my neighbor to sign off on the plan before Dakota would do the work. The fencing crew came on a rainy day to put in the post-holes. A week later they came to build the fence (on another rainy day). Because of the way the retaining wall went in prior to this fence project, Dakota had to modify the layout of the fence from our original blueprint, but they did a marvelous job with it. They sent very experienced people and I was very much at ease letting them make certain decisions without me in a couple problem spots - letting them figure out the best way to build and what would look the best. Overall, I am extremely pleased with the look and quality workmanship of the new fence, and the dogs like it too. I've gotten many complements on the fence from my neighbors all around. Dakota offered a discount for being an Angie's List member.

It started on time and ended on time - it took about a month. First, I had a spare toilet installed in the basement so I had something to use while my only bathroom was torn down. At the same time, I had a new laundry tub installed in the basement, and the old concrete one removed. Plumbing was all brought up to code as well. When the project started, Bryan provided me with a schedule of the work to be done from start to finish, as well as contact information for all the subcontractors. Everything was done on schedule, and inspectors showed up on time so the project went very smoothly. My house was built circa 1925, so my one bathroom is very small. The tear down to the studs took one day. There was one hiccup in the project, and it happened right after the tear down. During the middle of the night, a shut-off valve failed, so I woke in the morning to hot water spewing out of one of the valves. Thankfully, there was a hole in the bathroom floor to the basement, so most of the water simply ran down to the same area that I had cleared out to install the toilet. Really no damage in the basement, as all the water eventually ran to the drain down there. There was some damage to the finish of the hardwood floor right outside the bathroom on the main floor (the water was spewing that direction), but very minimal. I called Bryan at 6:15 a.m. that morning to tell him what happened. He and the plumber arrived in about an hour to finish cleaning up and fix the problem. The plumber subcontractor was great - just in case he also replaced the valve at the water main. This was the only problem I experienced in the entire project. Bryan brought in subcontractors for the plumbing, electrical, and tiling. I had picked out one tile pattern, however the tiling sub advised that I use another which actually would look better, and would save me a lot of money. I am very happy with his suggestion. I got great advice about what toilet to buy, as that was the only fixture I cared about (wanted something reliable, higher quality, low-flow). I wasn't picky about the sink and bathtub - I just took what the plumber advised. I ended up with a Kohler toilet. Can't remember the brands of the sink (wall-mounted) and bathtub. But they look great. I had picked out Kohler faucets and wall fixtures. I purchased all Kohler items through the plumber, so warranty would go through him. (Might have been cheaper to buy myself, but I didn't want to worry about paying extra labor costs if in a warranty time-frame) Bryan and I went over early where I wanted the towel rungs, shelves, etc. to go, so before they put in the wall he was able to install something behind that would allow for easy, strong hanging. The bathroom exhaust fan was new - they decided to build a box for it and send the exhaust through to the side wall of the house. It's a Panasonic fan - very quiet. I had an LED light fixture (with dimmer) installed over my re-finished medicine cabinet (I re-finished this myself). I took the mirror from the medicine cabinet to Alchemy Mirror Resilvering in St Paul. It's kind of a vintage medicine cabinet and I liked it. Besides, I didn't find anything I liked better anyway. So I fixed it up to look like new. I also had Bryan install some small cabinets over the door that would accommodate toiletries. They look great - custom built with beadboard on the front. I'm really happy with these, since my house has very little storage space. I did all painting myself. I also had a shower screen installed and I did a lot of research on this (had only used a shower curtain in the past). A friend suggested I look into the screens of the ilk that are used in small bathrooms in Europe. I found two manufacturers in the US that did these - Kohler and another manufacturer in Florida. They both looked like great options for different reasons. The Florida-manufactured product was half the price of the Kohler Minima screen. However, the design of the Kohler Minima shower screen was fantastic. The Kohler Mimina screen is a tri-fold screen that folds back accordian-style when not in use, so it makes it easier to clean the tub, and also isn't in the way when taking a bath. I opted for the Kohler Minima screen, which I purchased at Home Depot. Bryan had never seen or installed these screens, but he said he was always willing to try new things. He installed the screen and I am so very happy with it. It works exactly as I had hoped. When in use, the shower water stays in the tub area and doesn't leak behind the screen anywhere. I had looked for reviews of this product everywhere, including calling Kohler asking for referrals (they couldn't give me any), and calling other plumbing contractors. I found none. So, my review is that this product is fantastic - looks great, is excellent for small spaces, works as advertised, and installed relatively easily (took two people who followed Kohler's instructions exactly). Bryan and crew cleaned up the workspace every day. I have two dogs in the house and the crew was good to them as well. Some of the caulking around the tub and sink shrunk quite a bit in the first few months, leaving some gaps. Bryan came and patched those up for no charge. All in all, I am extremely pleased with how smoothly the project went from beginning to end, and I like how the bathroom looks.

FAQs for treehouse building projects in Osage, IA
The average cost to hire a handyman ranges from about $40 to $140 per hour. Average project cost ranges between $180 and $700, but the cost per hour and per project depends heavily on the type, size, and complexity of the project. The pro’s experience level and your location also factor into how much a handyman charges per hour or per project. You can also expect to pay higher rates or additional fees for emergency services, or around periods of high customer demand, like holidays.
One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.
Typically, it’s more affordable to buy an existing home than it is to build a new one. New construction loan interest rates tend to be higher than interest rates for traditional mortgages. Additionally, the cost of materials is likely higher when building a new home than it was when an existing home was built (unless it’s a very new one). You’re also paying for all new appliances, finishes, permits, inspections, and connections for water, gas, and electricity.
Knowing if you need an architect for your project can be tricky, especially if you've never worked with one before. In general, small remodeling projects like replacing fixtures typically don't require the expertise of an architect. However, larger projects, like moving walls or adding an addition to your home, should include an architect to ensure the project is structurally sound.
The cost to build a detached garage for two cars costs about $26,400 on average. Prices range from $19,200 to $33,600, depending on your location, the garage size, height, materials, and site prep required. Additional cost factors include any plumbing, electrical wiring, and insulation. If you need to build a concrete foundation for a new detached garage, you can expect to pay $1,000 to $8,600 for this essential addition.
