Q. Our home inspector said that parts of our sidewalk are a potential trip hazard. We think that he is being too picky and splitting hairs. What do think about cracks in sidewalks?

A. Simple cracks in a concrete sidewalk are not necessarily a problem unless they become large enough to catch the heel or toe of a shoe or the tip of a cane. Cracks normally indicate movement in the sidewalk, and are fairly normal. Most sidewalks that are more than 20 years old will have some cracks. On the other hand, upheavals in sections of the sidewalk can be a liability. Concrete sidewalks typically will have expansion joints at regular intervals. These individual sections of concrete can rise or fall as much as three inches in some extreme cases. The most common reason for upheaval is tree roots. The opposite problem is caused by subsidence where the ground beneath the slab sinks. An upheaval of more than one inch can become a dangerous trip hazard, and a liability to you as the home owner. This type of trip hazard is particularly dangerous at night. In my practice, I always explain this to the client, and encourage them to make repairs.

Q Our home inspector recommended that we install a chimney cap on the older home that we are buying. The chimney has not had a cap in it’s 60 plus year life, so why put one on now?

A In my practice as a home inspector, I always recommend the installation of chimney caps. Chimney caps serve a variety of purposes. They keep animals such as birds, squirrels and rodents from entering the chimney and in some cases the crawl space. A 60 year old home may have had an oil-fired furnace in the crawl space or basement which would have been vented through the chimney. The vent pipe opening provides direct access for critters. It is not unusual for rodents to crawl down through the chimney into the crawlspace seeking a warm place to nest. Chimney caps also keep out rain and debris such as leaves that can collect in the flu. Chimney caps also serve as spark arresters. Most caps are not expensive, and your local chimney sweep can recommend the one that is best for your chimney.

Got Attic Mold? How to Diagnose Common Sources.
By Mark D. Tyrol, P.E./Battic Door Energy Conservation Products

It happens to countless homeowners around the end of the year – you make the annual visit to your attic to collect the holiday decorations and what do you find? Spots and blotches covering the bottom of the roof sheathing. Worse yet – it turns out to be attic mold! What does energy conservation have to do with mold in the attic? Well if you take a step back and consider how the house behaves as system, they are often directly related. Building science experts have long been using the “house as a system” approach to diagnose the cause and origin of building defects. For example, ice dams. These are often caused by warm air seeping into the attic which causes the snow and ice on the roof to melt. The water drains to the edge of the roof (which is colder than the rest of the roof because it is an overhang and not warmed by the attic), freezes and creates an ice dam. As this process is repeated daily, the ice dam grows larger. Eventually water is forced under a shingle where it can seep into the house. Understanding how the house behaves as a system and the various causes and effects is necessary to diagnose most building related problems. But how about that attic mold? How did it get there? Mold requires chronic moisture to form and to thrive, so source(s) of moisture must be present. Possibly the moisture came from outdoors. The roof is newer and a quick check of the roof shows no obvious damage or leaks. Possibly the moisture came from indoors. During the heating season, the interior of the house frequently has high moisture levels, especially bathrooms and kitchens. A quick check shows that all bathroom fans, kitchen vents, etc. are properly ducted completely outdoors and not into the attic. The amount of insulation looks good and the attic is well ventilated. Don’t give up – you are almost there! Remember the house as a system? You know that warm, moist air is in the house, but how is it getting into the attic? By air leaks! Air leaks are the leading source of energy loss in most houses, and a frequent source of chronic moisture that can cause attic mold. Most homeowners are well aware of air leaks around windows and doors (especially old ones), but many overlook the numerous gaps leading directly into the attic! Have a look around the attic and you may find large gaps around recessed lights and fans, holes where wires or pipes are installed, even large gaps around the chimney. And don’t overlook the whole house fan and especially the folding attic stair - a big, uninsulated hole in your ceiling that is often overlooked! These gaps can add up to a large hole that allows warm, moist air from the house to flow right into the cold attic. The warm moist air condenses on the cold roof sheathing, creating chronically damp conditions that can lead to attic mold growth. And the energy loss – it can be like leaving a window open all winter long! Seal these air leaks and you stop a significant moisture source. And just think of all the energy you can save and the cold drafts you can stop! Mark D. Tyrol is a Professional Engineer specializing in cause and origin of construction defects. He developed several residential energy conservation products including an attic stair cover and a fireplace draftstopper. To learn more visit www.batticdoor.com

Big events and holidays can often mean big spending. A little pre-planning can help to ease and avoid financial pain. To the left are some worksheets that may be used when planning holiday or big event spending. In the meantime, here are some other tips for not overspending:

Set a Limit - Before any spending spree begins, make sure you know your limit. Set your cap a bit below as last minute expenses may arise. Did you account for mailing the gift? Gift wrap? The unexpected can creep on you before you know it! Also, take a look at how much you have spent in the past. Was it too much? What expenses surprised you? Asking questions like these will help you plan for the holidays and events to come.

Make a Gift List - Instead of hoping for something to catch your eye, keep a list of gift ideas. This way you will know what you are looking for and be able to better preplan the budget. This will also prevent buyers remorse - sometimes that gift that seemed like a great idea when you were in the store may not be so great when you sit down to gift wrap it.

Pay Cash - Credit cards are easy to use but not all of us are good at paying them off as soon as the bill comes. Taking cash helps you stick to your budget. Another alternative is the prepaid credit cards that you load with a limited amount in advance. Many also find these pre-paid credit cards a nice alternative to use for online purchases for extra credit protection.

Shop Early or Late - Depending on how far in advance you like, plan to shop either in advance of the holiday season or post-holiday season with the next year in mind. This will allow you to stick to a budget and not get caught up in last minute buys. It will also relieve a lot of the stress that comes with shopping during the busiest shopping days of the year!

Allow Time for Shipped Gifts - Plan ahead if you are shipping gifts to friends and relatives far away. Waiting until the last minute will mean more expensive postage to get gifts to the door on time.

Take Time to 'Comparison Shop' - Some of us get our list together and then just want to get it over and done with. Be patient, compare store prices and options before you go out to buy. This will help stretch that budget further.

Be Creative - Have fun with your gift ideas. Consider homemade or crafted gifts; however, don't forget the time involved making these items! Or make your own gift baskets - know a lot of chocolate lovers? Instead of buying a pre-made gift set - make your own basket of local chocolates or goodies.

Many years ago when I was doing maintenance work for a large property management company, I got a call to look at a clothes dryer that was not working properly. The tenant said that her clothes were just not getting dry no matter how long she ran the dryer. What I found was that the dryer lacked a lint screen, and the flexible vent hose under the house was sagging considerably and had been trapping moisture and lint for a very long time. The more moisture that became trapped in the hose, the more it sagged. The result was that the hose had become completely blocked by an oatmeal-like mixture of lint and moisture. No air could pass through this blockage, and the dryer could not do it’s job. In this case, replacement and proper routing of the vent hose solved the problem. When the proper flow of air is blocked, the clothes dryer has to work harder to dry your clothes, and this could lead to premature failure of the appliance, and in some cases could cause a fire. Whenever you have a home inspection, be sure to ask the inspector to look at the dryer vent hose, and it’s also a good idea to check it at least once a year.

As many of us look to stretch our dollar a bit further our money spent on entertainment is often cut. However, entertainment is a good way to relieve stress and get a quick break from the real world. Increasingly, the fee paid for an internet connection is offering a bigger return on the entertainment dollar. Improved connection speeds have created a mushroom of online content that allows users to watch streaming news broadcasts, missed TV shows, webisodes, viral videos (i.e. YouTube), free online games (and competitions), blogs and chat rooms - to name a few. Everywhere you turn, everyone is trying to get their movie, TV show, 15 minutes all noticed on the web. Television alone has morphed from episode summaries and casting lists on a single webpage to deluxe sites with missed episodes online, behind the scenes footage, games, screensavers, additional back stories and character development, and much more. So who is leading the pack with the best sites and content? Who is side-stepping the pack altogether? You might be surprised!

The Usual Suspects
Below is our ranking of the major broadcasting stations that are easiest to use and include extra online content.

1. NBC.com http://www.nbc.com/ NBC has a slick and clean menu and you can easily find episodes of your favorite shows. A great plus is that you can watch a whole season if you got lost a while back and need to catch up. Also, you don't have to watch the show the same week it originally airs. Videos load quickly and offer chapter selection to jump where you left off or skim through with ease. 
2. ABC.com http://abc.go.com/ The website is clean and easy to navigate. A big disappointment is that not only does the user have to sign an agreement but then download a special plug in just to watch online episodes. The entire site has a much more proprietary feel to it. However, they did redeem themselves a bit by allowing access to episodes from previous seasons for one of their most popular (and confusing) shows 'LOST.'
3. CBS.com http://www.cbs.com/ CBS has a fairly easy menu. The best is to go by show as viewing directly by video is a bit more messy and makes it harder to find past episodes. The option to watch TV and chat at the same time is slow to load (I gave up after two minutes of the loading icon spinning). Video without chat loads quickly and is just as fast as the other stations. Plenty of content about shows but the webpages have an older point-and-click menu that takes a bit longer to navigate. There wasn't a lot of clarity in the order of episodes if you were trying to catch up for the season.
4. FOX.com http://www.fox.com/ A slick moving website that is easy to navigate. However, FOX allows access to fewer full episodes then the other stations. The individual show websites offer a lot of extras but are not as clear to navigate.

Cable Networks
So if you don't subscribe to cable, who gives you the best online?

1. Discovery Communications Group Discovery Channel - http://dsc.discovery.com/ | The Learning Channel - http://tlc.discovery.com/ Animal Planet - http://animal.discovery.com/ | Science Channel - http://science.discovery.com/ This family of websites has a similar menu and limited selection of full episodes like FOX. However, the fact that current shows with new content is available is a plus compared to other cable stations. Overall, a great way to get highlights of what you're missing for chats around the water cooler. Also, the extra games are a nice touch.
2. Comedy Central http://www.comedycentral.com/ Full episodes are available for most shows. The individual shows do keep separate URLs which made it a little harder to navigate back to Comedy Central. However, all offered complete sites with extra content.
3. Disney TV http://disney.go.com/index This site has a slick design and offers plenty of content including games and fan pages for their most popular shows. One negative is there is almost too much content. Many 'teaser' videos play when the user enters a new page without being selected. Although some full episodes are available online, they are not necessarily in discernable order.
4. Nickelodeon http://www.nick.com Plenty of fun games and video bites for kids. Like Disney, there is background content that loads as soon as you enter a page. The pages are busy and harder to find content.
5. A&E TV http://www.aetv.com/ Not the easiest navigation at first. However, more episodes and clips of episodes are offered then on some comparable cable sites.
6. USA Network http://www.usanetwork.com/ A couple to a handful of episodes available of USA original shows. Some are available without commercial interruption which is a nice touch. However, not all series offer episodes for online viewing.
7. Bravo http://www.bravotv.com/ Some behind the scene information and recaps. Videos are offered with some full episodes. However, the navigation of videos is not user friendly and is geared more towards a fan who knows what they are looking for on the channel.
8. TBS.com http://www.tbs.com/ Again a required download of a plug-in before being able to view videos. Basically a collection of a few variety shows and reruns. There is not access to the movies, only their schedule.

A Brand New World
Sites without a presence on television but offering television/movie entertainment.

1. TV.com http://www.tv.com/ There is definitely more content on this website then some of its competitors. This site has a larger variety of shows and even news broadcasts are easy to search and view here. TV.com offers an easier navigation if you want to find information and summaries of a particular television show. However, the video interface is not as friendly.
2. Hulu.com http://www.hulu.com/ Hulu offers episodes of series from all different TV channels. Episodes are separated by genre rather than channel, but an easy search will help you find your favorite quickly. Interestingly, some episodes will load directly from Hulu whereas others will take you to the home website making Hulu act more like a search engine. An added plus are the movies. Many of your re-run favorites from Sunday afternoon can be found here. Load time is good, even for full movies.
3. Boxee http://www.boxee.tv/ This is a free membership website that dose require users to download their program. It checks all your media on your computer and then creates a one stop area for everything from photos to music. With an open source code it is intended to be manipulated by users so they can add user generated content. However, it is not really ready for all computer systems at this time and was overall frustrating to install. PC to TV or TV to PC? Considering the competition for your entertainment dollars, it should be no surprise then that many TV's offer WiFi connection to your computer to make certain you can enjoy all these extra goodies from the comfort of your couch. However, some computers are also pushing their new models of All-in-Ones aimed at being one-stop entertainment centers. These new computers are offering bigger and better viewing screens, more compact CPUs and easy plug and play for cameras, music players (iPod, Zune, etc.), and much more. Depending on your budget and your pocket book, there are some wonderful choices on the market already.
