We were a bit gun shy about leaving our son there as a baby, but things went well overall during the early years there. Our daughter had a good time there, but things changed about a year ago when a new director came in, which was just when our daughter was leaving. Something happened with the senior staff a bit over a year ago. An asst. director left immediately, and it didn't seem to be a voluntary exit, and a secretary who was really much more than that left very soon thereafter. The person who was director was demoted to asst director and worked for the new woman who came in. When this happened there was a major flushing out of personnel, some voluntarily others, it would seem, not. Under the new director the climate in the place changed, people were fearful of their jobs, it seemed that they were looking over their shoulders. The quality of the learning experience for the kids changed. With my daughter there was a much more concerted effort to do lessons, show work that was done by the kids, you could tell that there was learning going on in the place. That seemed to stop with the new director, there was little indication of anything being done with the kids, though they were safe and kept busy with whatever was available for them to do on site; bottom line, there was not the sense of things happening there that was the case before. Suddenly there seemed to be a big emphasis on cleaning over doing lessons with the kids, not that cleanliness ever seemed to be an issue before but that's where the energy seemed to be going with the staff. We watched good people, at least per our perception of them, go out the door, and while I appreciate that we would not be privy to the reasons for this it was disconcerting to see teachers who seemed to work well with the kids go. There are good people at BH, but for kids beyond the age of 2 I would only reluctantly recommend it. Administratively it needs to get it's act together. There was no means to pay electronically (unless you had your bank cut the check from the bank itself, and in the end that didn't save any time, and still required you to wait until the check cleared before it was off your books) or pay with anything but a check that you dropped in a box every month as you came in with your child. In my book that there isn't a means to do a direct bank transfer from a checking account to BH, or, wonders of wonders allowing for credit card payments, is beyond inexcusable for a business this size. That you have to be mindful of making your payment with a check as you come in the door, more often than not frazzled over dealing with a baby or a screaming child, just doesn't help and, again, in this day and age shouldn't be necessary. It has terrific near prison grade security. The daycare sits on the Health and Human Services campus on Fisher Lane, which means that you have to go through the security gate with an electronic badge when you come in to get your child. Not a problem if you have a government CAAC card (in all fairness, this BH's mission is to support government workers), but otherwise you have to get a badge from HHS security and renew the badge EVERY year, no simple thing as you have to come in to have your picture and finger prints taken to get the badge, and then wait a few days and come back to get the badge. On one level you think, "Wow, what great security, that should make me feel comfortable about leaving my child here", but then how much security do you really need, and given what you have to go through for this is it worth it? I say no, but others may disagree.

Security Door Installation reviews from real Angi homeowners in Potomac, MD
I got locked out of my house. I called Liberty Lock And Security Inc. in Rockville, MD. They were nice to me over the phone. The young lady referred me to a gentleman over the phone that said they charge $89 a service call and $169 an hour for labor. A gentleman named Darryl showed up in 30...

Tom was prompt, courteous very personable and professional. He replaced the adjustable kwikset deadlatch on the door and it works perfectly now. I would not hesitate to recommend Kensington-Wheaton Lock & Security.

This was the first time I used Walker Furniture Services. Rusty came for the estimate on time. He took my doors back to his shop and kept them for less than two weeks so they could dry. He did a beautiful job in installing plywood to secure our safety in place of our missing front doors....

"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"We were looking to increase our attic insulation and met The Home Doctor Company at the Capital Remodel and Garden Show in February 2025 as well as some other companies. We consulted with several companies and decided to go with The Hone Doctor for our attic insulation. The company rep, Chris Lear, was very good explaining what they would do and why our attic needed R-38 insulation. I knew we needed more but did not realize our attic was only R-13. I have worked with numerous contractors before on projects and felt this was a really good company plus they have great reviews. The installation of the attic insulation went very well. They do install siding as well but decided to put this project off for now. Would highly recommend this company."

Security Doors questions, answered by experts
Yes, door sills are necessary components for most doorways. They serve several crucial functions, including weatherproofing, structural support, and aesthetic enhancement. Without a door sill, you risk water infiltration, drafts, and potential damage to the door and surrounding structure. Therefore, while they may seem small and often overlooked, door sills play a significant role in maintaining the integrity and functionality of a building's entryways.
You don’t need to shim both sides of a door, but it’s always a good idea. Wall framing is rarely perfectly plumb, and shims let you make minor adjustments to get your door perfectly level and plumb. This will ensure the door swings open and closes smoothly. You can also use shims on both sides of the door you’re installing or adjusting to center it in the wall opening.
Solid-core, hollow-core, and panel doors offer options for various needs and budgets.
The L marking on a door closer stands for latch speed and the S marking stands for swing speed. These two letters inform what part of the door closer you may be adjusting. The latch speed being the short final swing the door makes before closing and the swing speed being the long swing of the door when closing.
Security experts recommend deadbolt door locks on entry doors because they provide the best security. Deadbolts can prevent most types of forced entry and make your doors harder to lockpick.
